Ludum Dare 32 — April 17th-20th, 2015 — Theme: An Unconventional Weapon

chromenopePSA: As of Chrome 42 (Released April 14th), NPAPI plugins are disabled by default! That means Unity Player, Java, and Silverlight games will not work in the Chrome browser! That said, Flash in the Chrome browser continues to work fine (PPAPI).

To Developers: Consider using HTML5 and WebGL instead. Having troubles with the export? Don’t worry. See Ports below.

To Players: A workaround is to enable NPAPI plugins in your Chrome settings. Click or Copy+Paste this URL in to a tab:


As of September 2015 however, this option will no longer be available.

Other browsers (Firefox, Internet Explorer, Safari) and Flash are unaffected, but FWIW there is no Unity Player or Silverlight for Linux.X

Sound Runner

by Makay - Jam Entry

- Please read the controls below before you try the game or you won't know how to play as there's no in-game help.
- Pay attention to the top overlay as it will be very useful right from the beginning!


Background story:
Dr. Paul Felix is an Intelligent Systems researcher who managed to build robots who were capable of making decisions of their own. However, the robots soon got too intelligent and one morning Dr. Felix found his lab completely destroyed. Soon he found out that the robots had escaped and started building even smarter and stronger robots who were capable of killing people and steal their vital energy in order to sustain themselves. Once he saw this scenario, he quickly called out Epson, The Sound Runner, in order to save humanity and the world!


The objective of the game is to use Epson's keytar to kill robots in order to save the world. Epson's keytar is able to absorb energy from every robot it kills, however if you run out of energy you're pretty much dead. If you collide with any robot/obstacle you will also die instantly.

PS: This is actually an infinite runner so there really isn't an end. It's still fun to try and beat your friends' scores though!


Space bar: Start/restart/pause/resume the game.

Right/left arrows: Jump right/left in order to dodge robots or obstacles. (Or get in front of them for ultimate killing!)

In order to kill the robots you need to use the number keys on your keyboard to match the corresponding sequence.
Below are the key combinations to kill each type of robot and their score multipliers.

NOTE: The top overlay will show you the sequence you need to execute in order to kill the robot right in front of you, so you don't have to memorize any of this. These are here just as a reference.

- Minibots: (10 points)
. Green: 1 (x0.5)
. Grey: 1 2 (x1)
. Blue: 1 3 (x2)
. Red: 1 4 (x3)
. Purple: 4 2 (x4)
. Golden: 3 1 (x5)

- C69: (20 points)
. Grey: 1 2 3 (x1)
. Red: 1 3 2 (x2)
. Purple: 1 4 2 (x3)
. Golden: 1 2 1 (x4)

The future of humanity is in your hands! Good luck!


(Awesome) Music: Cottonmouth - Timeshift (


This game was entirely made in HTML5 by me and two more friends from college.
We used three.js (WebGL) for the graphics and a couple of small libraries for the rest.
I wrote most of the code while one of my friends made all the textures in the game and the other worked on the HUD.

It was the first game we ever made (besides Pong) and we had a great time doing it. We know it is far from perfect but we're really proud of what we accomplished in this first attempt.
I want to keep working on it after this but we'll see if that happens.

I really hope you enjoy the game and please leave some feedback! We'd love to hear everyone's thoughts on this!

I can't seem to get it to run! I only get a black canvas with a few grey UI elements.

Worth noting, I am running Chrome 42. I tried disabling AdBlock to no avail.

^Hit space to start it when you get the black screen

It won't work on Chrome because it runs on WebGL, sorry :(

HIT SPACE AT THE BLACK SCREEN EVERYBODY!!! Its incredibly hard unless I am not understanding something. Quite a nice tune, though.

Makay says ...
Apr 21, 2015 @ 4:35pm

It is really hard in the beginning but after a few runs you memorize all the sequences and it gets really fun, trust me!

sanojian try to follow the combinations that appear at the top of the screen! It's all about motor coordination :P

Encountered the same startup bug as many other commenters, the use of numbers keys could've also been explained a bit better :D

However I find that the mechanic is actually quite nice and visually everything runs silky-smooth. I think a bit more time is what this game needs.

Thank you very much for your feedback! The black screen isn't actually a bug, it was meant to be a start menu where it explained how to play and had some options but we ended up not having enough time to do it.

I definitely agree with you that this needs more time in order to be a "good" game but I hope you had fun anyway.

sanojian says ...

I must not have much motor coordination ;-).

@Makay: It works fine in Chrome. Chrome supports WebGL.

Nice number-masher, but gets a little repetitive. Reminds me of the flash game Run for some reason. With some work (improving the abrupt game over via a life system, maybe) this could make a good game.

I coded some fixes into the game because people were having issues trying to play it. The gameplay was not affected at all.

Great game. Could do with some ramping difficulty instead of being attacked by all variations at once, but besides that the gameplay is great.

I really like the flow of the game and partially the environment, The buildings look interesting and the fade out to darkness is nicely done. I find gameplay really hard in the beginning. Some instructions ingame while playing would be cool.

I got a score 260!

The graphics were cool though his running animation needs work. I like the concept it can be pretty fun at times, though I wish the robot killings would be more intuitive or at least mentioned in the game. It is hard to memorize all the codes. Overall, it is a solid piece and I did have fun.

Overall I like theme usage and concept, it was little hard for me to get my head around to get far enough in only because of my backward guitar playing mind. Love to hear some SFX play when you use the key tar and make different riffs based on different robot patterns pressed. Also love to hear the music continue after you die since I didn't hear more that 45 seconds of it :(

Great job overall, keep up the good work!

Neat concept, great music and good graphics. The gameplay for me was slightly difficult to get into although I do see the potential for fun, especially with that music. I was confused about the numbers, and even after reading the how-to I found I was unable to use the num-pad, which is what I was wanting to use for a game like this. Great job!

Very cool idea! And excellent music.

Nice concept. Really wished the numberpad worked though :(

Apr 23, 2015 @ 4:04am

Really dug the control scheme; very original. Nice variation on the endless runner genre. One of my favorites I've played so far!

The numbers should be placed in the middle or similar, so it's easier to keep track of them while looking at the "street".

This was hard !

The controls are fine and the game is interesting. However, its quite hard to kill an enemy not in your lane since you dont know the sequence to kill them before being in front of them. I'd recommend being able to see the sequence on each unit on screen somehow.

Otherwise it ran great. Good job on the entry !

This was cool, would have been nice to have the button sequences nearer the actual character so that you didn't have to spend the entire game watching the top of the screen though :)

Mini Submission FAQ

TEAMS: Teams entering the Jam should pick a single representative to submit your game, or create a team specific account you can share. We currently do not support Team Voting, but sharing an account and together playing and rating games is acceptable.

CAN I ENTER BOTH EVENTS?: You should pick 1 event, whichever you think it’ll do better in. If the idea is strong, and everything plays well enough, you can go Compo. If you’re a perfectionist, and would prefer people to play a more polished game, do the Jam. Historically, more games are entered in the Compo, but with more people and more time, Jam games have the potential to be better (that doesn’t mean they are). Many solo participants do enter the Jam.

If you made 2 games, unfortunately, the website doesn’t support multiple submissions per user. To submit your 2nd game, you will have to make a 2nd account. Only do this if you made 2 games. Alternatively, if one game is better than the other, then consider just entering the better game.

CAN I KEEP WORKING UNTIL THE DEADLINE?: Yes! Immediately after the 48 or 72 hours, we do something called Submission Hour. As the name suggests, it’s an extra hour for you to package, upload, and submit your games. If there were catastrophic issues trying submitting your game, or you misunderstood how submissions work, that’s okay. It happens. We’re flexible. If you need advice, check with the folks on IRC. If you need an admin, get in touch.

CAN I KEEP WORKING ON MY GAME?: Oh definitely! You should! But for the sake of judging, keep the Compo or Jam version around. You can include a link to the Post-Compo/Post-Jam version of your game on your games page, but sure your main links are the original version.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate at least 20 games to improve your visibility (Coolness).

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crashes, win condition, or tiny bugs after the deadline. In a sense, this is like “porting” to support more players. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just fixing mistakes you should have caught had you been better rested.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up. Alternatively, if you just posted it, wait a minute. The cache may not have refreshed yet.

NOT LOGGED IN?: If you get a message about not being logged in, even though you are, it’s because your web browser cached the non-logged in page. You can fix this by either refreshing your cache or clearing your cache. CTRL+F5 in many browsers. Chrome is a bit more work. Press F12 to enable Developer Mode, then you can right click on the refresh button and select “Empty Cache and Hard Reload”. This option is unavailable if you are not in Developer Mode.
