Almost half of the judging weeks has passed, and I’ve seen many great games. Unfortunately, I couldn’t rate games this week, and as I wanted to keep a pace of 20 games rated per day, I’ll “have to” rate many games this weekend. So, in order to make this task more enjoyable and to keep experiencing great games, please tell me :

What are the best games you’ve encountered in this LD so far?

Some of the best LD#25 games I’ve seen during those 10 days are:

– Compo –
Atomic Creep Spawner!! by deepnight
Video Games Cause Mass Shootings by adnzzzzZ
They All Fall Down by Fififox

– Jam –
Demon Quest by Carduus/Thotor/Mathieu Hallouin
Seeds of Wrath by 01101101 & friends
The Rise and Fall of Professor Moriarty by ProfessorMoriarty

Play / Rate | Timelapse | Demo | Postcompo version


I’m currently working on a postcompo version for my LD#25 game: Blob Revolution. I’m fixing the “bugs” highlighted during the rating weeks, adding some content, etc. This post will keep track of my progression. I’m obviously accepting any suggestion 😉

Blob Revolution – Postmortem

Play / Rate | Timelapse | Demo | Postcompo version (progression)


LD#25 was my second participation, and the second game I created. Before participating at the 24th Ludum Dare, I couldn’t just go and make a game. I am terrible at drawing, and always wanted to find a graphist before starting to code any game.

Ludum Dare forced me to be a graphist, and even a compositor. I learned that I was in fact capable of creating my own games without any help. And now that I have my new computer, I’ll be able to start making more games soon, with Haxe instead of HTML5 (the only thing my previous computer could run..).

You can find the timelapse here:


What went right

Time management.
Unlike LD#24, this time I was able to have a finished game before the compo deadline. I spent way less time procrastinating, something like < 5% (40% for LD#24). I avoided spending too much time on a bug, by fixing it the easy/quick way.

Playable at any time.
I rushed over a playable version the 4 first hours of this LD, so that I had a game to submit at any time after that. Using git gave me that opportunity. I could then add content without worries, even 1 hour before the deadline.

Kept it simple.
I am no graphist nor compositor, so I kept both simple to be able to have a fair amount of content in the end. The background took me a few minutes (The Gimp), vectorial shapes were made easily with Inkscape, and sfx + music took me less than 15 minutes in total (besides the two computer crashes). And in the end, I’m quite satisfied with the result =)

Focus & Health.
Although I have headaches every day lately, I haven’t had any problem during this Ludum Dare. I was able to focus the whole weekend, without starving (couldn’t buy snacks for LD#24), with no exhaustion while not sleeping much, with sugar (candies *o*) and with cigarettes to help me fight my hyperactivity (didn’t have any for LD#24). Those helped a lot against procrastination.


What went wrong

Less catastrophic than LD#24, but I had no good ideas. I had some, but too risky (involving good IAs) or not that great (the one I chose). I needed some drawings and more story telling to make this one really fit the theme, but couldn’t do it.

I forgot to launch chronolapse for the first hours, lost some more hours of screenshots with ffmpeg later, and forgot again to launch it after sleeping.. My timelapse could have been exhaustive, but well.. I’ll be more cautious next time x)

Computer performances.
My computer gave me a hard time again. Poor performances implied creating a game without knowing how it would really run on a decent computer, and resulted in a game a little speedy. I had a crash while trying to make the music (when my timelapse ends), and a second one while trying again. I ended up with only my test music (I was trying the instruments), and I used it in the submitted game. It was funny to see that it pleased some players xD

I’m in for my 2nd LD

Posted by (twitter: @_kLabz_)

Last time — for my 1st LD —, I ended up screwing many things…
I hated the theme, I spent more than half of my time procrastinating (not even counting sleeping time here), I wasted too much time on an optional feature, and I didn’t train at all.. (plus, I didn’t have snacks / coffee / cigarettes ’cause I was kinda broke =/)

So, for this LD I’ll be using box2d-js to save time on the physics part. Didn’t want to use an external lib, but well as always I realised LD was coming only 6 days ago… I’ll try to stay focus most of the week end, eat well, sleep well, code well :)
Still need to train hard for audio.. Last time Mathieu Hallouin did my music, and it was awesome, but this time I wanna compo so I’ll have to do my best to come up with some music and sfx =/

  • Languages: Haxe + HTML5/JavaScript
  • IDE: Sublime Text 2
  • Graphics: Inkscape / Gimp
  • Audio: BFXR / beatlab
  • Libraries: box2d-js
  • Timelapse: Chronolapse

Postmortem #2: Tools

Posted by (twitter: @_kLabz_)
Tuesday, August 28th, 2012 7:28 pm

As it was my first Ludum Dare, I did not exactly use the tools I thought I’d use. Some weren’t used at all, some others not in the way I though it’d be used, etc.

  • Language: Haxe + Javascript
    Did not changed much, although I didn’t really use Haxe.
  • IDE: Sublime Text 2
    Really nice code editor, especially when you have to code for long hours (dark interface). Love the minimap too.
  • Graphics: Inkscape / Gimp / Wacom tablet
    Didn’t use my tablet at all. Only used Gimp for backgrounds, for a total of like 5 minutes. I started with pen drawing, then polygonal representation in code from those drawings, and then Inkscape for the sprites. Shouldn’t have. Should have done drawings -> sprites -> polygons, as explained in my postmortem.
  • Audio: LMMS / BFXR / Audacity
    I tried LMMS last week, it’s a great tool but I’m not ready to use it.. Didn’t like BFXR, so I didn’t use it either. As for Audacity, I used it to sync the enemies to the music Mathieu Hallouin made.. kinda unexpected use, but it helped!
    By the way, he did a really great job! Check out his LD#24 soundtrack, he worked on Prac Team‘s game too.
  • Libraries: None
    Didn’t use any library. I don’t like using jQuery and such when I only need like 5% of it.. But I think I’ll make my own game library for next LDs.
  • Timelapse: Chronolapse (?)
    Used chronolapse, and I kinda regret it. I’ll make my own LD-timelapse tool for next LDs. Timelapse video should be available soon by the way. I had to filter screenshots: even though I stopped chronolapse when I did real breaks, it still contained 30% of procrastination (games, facebook, watching lives, youtube, etc.)…
  • Coffee
    I didn’t sleep much, but I only drank like 5 mugs of coffee in 72 hours. On the other side, I drank so many liters of water that I couldn’t keep track! Water is great, even if you loose time going to the bathroom every 30 minutes xD

Overall, those tools were useful. But I’ll need more preparation for next Ludum Dare to do it the way I’d like. I suck at graphics and music, and as I want to compo I’ll have to train that. This time I had Mathieu Hallouin for the music and did not had much to draw, but I cannot continue like that.

Play/rate the game

First Ludum Dare for me.
I was initially going for compo, but I spent too much time procrastinating (currently making my timelapse video, and 30% of it was games, lives, etc. despite the fact that I paused chronolapse for every “real” break), and Mathieu Hallouin made me some great music so I entered Jam instead.

Hated the theme. Thanks for influence voters… Parallel Worlds would have been a perfect theme, but well.. next time?
So hmm. Took me some time to find something to do with this theme, something that I would be able to do with my pour level in graphics.


What was good:

  • Polygonal collisions. First time trying that, and it worked perfectly (see bellow if you disagree)
  • The music. Mathieu Hallouin is really good oO his soundtrack
  • I made it in time. I spent too much time procrastinating, but in the end I was able to publish my game in time. I could have published it in compo, but as I was sync-ing the levels to the music I wanted to use the music and so I had to enter the jam instead.


What went wrong:

  • Didn’t like the theme. But well, it happens…
  • Spent waay too much time on some things, only to end up dropping the idea…
  • No snacks. I have no money atm, so I only had pasta.
  • Started the LD tired and drunk. Not good 😀 Well, I couldn’t skip this birthday party.
  • Made the polygon representation before the images. NOT a good idea, even if it allowed me to work on gameplay before doing graphics. When switching to images, the polygon representation isn’t always centered and so the collisions apply on polygons but not on images.. To try polygon mode, execute this code : ld24.poly=1; with scratchpad or whatever. Doesn’t work on mothership, I added the sprite during last 30 mins and it didn’t go well…
  • Lost more than two hours fixing something that actually was working.. Just not on firefox with localhost -_-
  • My internet connection broke 5 minutes before the deadline.. Nice troll…


It was a great experience as a first LD, I learn a lot of things that’ll help me doing a good LD next time. I’ve got a game working, and I think I’ll polish it some time soon.

Before LD…

60 hours and tens of liters of water later…


Well, back to level design. Got 3 new ships to implement & 2 level to design.
Boss level is done by the way, and won’t be easy 😀

Hopefully I’ll have enough time to add some sfx & explosion animations…

Some progress #3

I wanted to post my game in compo for this LD (my first), but well, I’ll be jammin’ x)
So now I take my time and I’ll be able to finish my game the way I wanted it to be.

I’m changing some evolution mechanics, but here’s a [kinda] playable version :
Only “Level A” is available. Use arrows to move, space bar to shoot. The game isn’t really balanced yet, so it’s hard 😉


And hmm… a screenshot I forgot to post 😉

Some progress #2

Saturday, August 25th, 2012 8:22 pm

Nothing good today… lost 6~8 hours due to some math not going well (and in the end I just gave up on this), and tonight (well, already 5 am here xD) my firefox made me loose 3 more hours with html5 sound… although my code was good u_u

Anyway, got something playable, I’ll now add some content (new ennemies, sprites, illustrations, game background, etc.) and do some level editing + balancing.


Some progress #1

I wanted Parallel Worlds as this LD’s theme, but whatever, I’ll do with Evolution
Still have many graphics to do, so for now only the polygon view is available for the game elements :

Lost a lot of time with polygonal collisions, but now it works perfectly :)
My lack of sleep really is a pain in the *ss 😀

Getting ready

Almost time to go \o/
This LD’s beginning will be hard for me, as I’ll start tired and… drunk!
Not quite ready for graphics & music, but I’ll try to make something I’m not too unhappy with…

I’m in! (maybe…)

Unlike last 3 LDs, I should be available for this 24th Ludum Dare.
It would be my first time, so I hope I won’t mess up…
I’ll use the remaining time to train graphics & sfx, I’m really bad at it >.<

  • Language: Haxe + Javascript
  • IDE: Sublime Text 2
  • Graphics: Inkscape / Gimp / Wacom tablet
  • Audio: LMMS / BFXR / Audacity
  • Libraries: None
  • Timelapse: Chronolapse (?)
