I thought I would try to record a couple of videos / let’s plays of your games, played and rated by me and my girlfriend. I enjoy seeing my games played, so if you do too, add your game to my list. I will release videos on my YouTube channel as soon as we record enough footage. Also, we will try our best to be objective with each game, giving it our best try, weighing its pros and cons before putting them in a comment for you. :)

(It’s our first time too, so hopefully we manage this :D)

fixed typo


Timelapse coming soon!

So, this was fun. Even though I missed 5+ hours because of family business, I pushed till 3+ in the morning on both nights. Yup, European timezone. I did spend quite a lot of time on the backgrounds / art, so I hope the ratings reflect that. But it cost me some polish – I had to rush the endings in the last minutes, test them, fix them, etc. The last minutes were very hectic. I did play around with the radio track for quite a bit, but I don’t regret it. It’s simple, but it sounds quite nice. And it’s officially my first game soundtrack ever! (That is actual music, not … deep sinewaves playing random patterns)



The story might be confusing, here’s how it was supposed to go:

  • You, the player,
    wake up in the jungle with cliché amnesia
  • You find a facility in the jungle, containing an ominous-looking and -sounding machine that makes you its ‘secondary agent’ by making you wear a VR headset
  • It tells you its objectives
    • Collect data
    • Archive
    • (corrupted)
  • You go ahead an explore the nearby hunting town, which is almost empty, except for 3 people (it’s off-season)
  • You find parts of the machine in the town, but the townsfolk won’t give them for free
  • As you talk to them, they grow more and more suspicious of you; they ‘disappear’ one by one – to you it looks like they just leave town or lock themselves up, etc. – it is actually the machine creating an illusion
    • In reality, it controls you through the headset, making you kill all the people and forget about it
  • You gather all the parts, it then reveals the final objective – Exterminate – and that you have already completed it
    • Cue footage of you killing everyone one by one / the VR illusion is turned off

I know, it’s somewhat ominous and doomy-feeling, I like that kinda story. Maybe it’s for the better that I couldn’t finish it 😀 Oh well.


Hope you enjoyed this game, looking forward to playing / rating yours!

Primary objective!

6-hour warmup game (+ I’m in)

Posted by (twitter: @AurelDev)
Monday, August 17th, 2015 3:37 pm



Yup, I’m in. Pizhul wasn’t really supposed to be a game, but I hope you enjoy it nonetheless :)

For my LD33:

  • IDE: TextMate
  • language: haxe / swf
  • timer / timelapse: shtime / shlapse
  • audio effects: sfxr? sox? code-generated?
  • music: code-generated (with my music library)
  • + tea, Opeth, Pink Floyd, walks with the dog

Have a blast, everyone.

In, I am. Also wallpaper.

It’s time again :)

  • Language / platform: haXe to .swf
  • Engine: none, save custom boiler-plates
  • IDE: TextMate, TotalTerminal, …
  • Audio: sfxr? code-gen?
  • Graphics: sketches, Photoshop
  • + Pistachios and Opeth

Aiming to get even better results than last time! (#11 mood, #31 gfx, #50 overall) Though that was already quite a success. As always, will try my best to add -real- music into my game … Maybe try a tracker of some sort? Other than that, hoping to research some AI-related stuff before the actual LD. :)

Good luck, everyone!

Also made a wallpaper, available in many different sizes here.

Cell #327 Results

Well this LD was pretty cool. Thank you, everyone who voted and / or provided valuable feedback :)

My results, compared to my LD30 entry, are better in every single category, except for innovation. I kind of expected this game to be considered at least somewhat innovative, as far as LD games go – I haven’t seen too many point ‘n clicks. (Resizing your browser window, on the other hand, … eh.)

Anyway, bitter feelings aside, just like with every single LD entry ever, I want to finish it one day! And I probably never will. But here’s to hoping. :) I am, however, working on someone else’s Post-LD game. Wish us luck!

Looking forward to the next LD!

Super sneak peek

Play here

(One hour for making a game is definitely not enough at all for a polished result. However, I believe this is good practice for rapid prototyping / any kind of gamedev jams with very limited time. It helps identify problems with your framework, workflow, the tools you’re using, your time estimation, et cetera. So I gave it a go, hopefully this could turn into a fairly regular exercise.)

Anyone here up for a challenge? :)

Oh yes.

I was –kind of– disappointed with the theme not being snowman this morning. Over the night I though of a whole nice story involving nightmares of a snowman shaped figure, then a horror as the snowman becomes more and more real, getting into your house, etc. Next time :)

Yet another “I’m in.”

Yup. Just so I can say ‘told you!’


(I like them, they’re just bad as a theme :ň)

But anyway, my setup:

  • Language: haXe (+ some boilerplate libraries which I seem to use in every project ever)
    I have been using AS3.0, with the not-exactly-optimal Flash IDE for a while now, it is time to switch. HaXe really is a nice language.
  • IDE: TextMate and Terminal
    Really all you need … even makes a timelapse!
  • Graphics: Photoshop CS5
    Yup, hate me for it. I should finally find / make a good pixelart editor, PS sometimes feels like a bit of an overkill.
  • Sound: sfxr / code-generated
  • Music: code-generated, if at all present
    I really hope one day I’m going to make a game with music!
  • Playlists to get me through: Pink Floyd, Porcupine Tree, Opeth, …

There. I’ve been fighting off this illness for a couple of weeks now, so I had time to get ready, write some basic libraries, get used to haXe and all that. My workplace might just end up being my bed most of the time.

Goals for this one:

  • Player-friendly, core concept and controls easy to understand
  • A goal / finish line to the game… Or infinite with sufficient replayability + high-scores etc.
  • Music?

Dare on!

Elemental Post-Mortem + Timelapse

LD30 Elemental screen1

Play now | Timelapse


Skipped a weekend worth of revision for my exams the following morning, didn’t really get to sleep for them either (cause European timezone) but … I think it was worth it :) When I was coming up with the concept, I imagined the resulting game to be a little more … dark, more atmospheric. In the end it is a bit different, but maybe that’s for the better. Seems to be more fun, the different worlds are noticably different in their palettes, etc.

The good things

  • it is incomplete, but I think it feels quite polished
  • I certainly want to develop this into a full game (like most of my submissions …)
  • I could implement the basic algorithms (pathfinding, particle systems, AI) without wasting too much time on them
  • was more productive than my previous LD’s – clocked 28+ hours on my timelapse
  • found out switching tasks often instead of focusing on just one for a longer time (and getting stuck) seems to help me

Elemental - character spritesheet

The bad things

  • STILL I was a bit too ambitious (like every single LD ever :) and wanted a bit too much – a levelling system, skilltrees for the different elements, five different combat systems …
  • I did spend a lot of time on making some graphics that didn’t even make it into the game
  • the last hour or two before submission hour were spent tracking down a stupid bug
  • I am not too good at UI design – kind of forgot about the players who don’t actually know the system – so, no HP bars for the enemies, and the fight system is a litle obscure at first

Elemental - GUI spritesheet

All in all, I am glad I participated in this LD, looking forward to playing + rating your games, as well as the next compos!

LD 27 – Thade – Timelapse

YouTube link

Total time: 22 hours, 19 hours, 35 seconds.
Frame taken every 5 seconds (16075 frames).

Thade submission page

So YouTube removed the music immediately after I uploaded the video (nice algorithm -_-) … then allowed me to remove just the track infringing copyrights … So I did that, then the resultant video was processing for an hour or two … And, in the end, the other video was just as silent as the first one! 😀

Yeah. So there, that’s why there’s no Pink Floyd playing in the background. I liked the music :(

Edit: oh goodie, now the music is back up, again. At least some of it? Edit 2: All of it. Make up your mind, YouTube! :I
