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

A Tale of Two Souls

by indigo - Compo Entry

A classic platformer with a twist. You have a gun - a soul gun - and after your kingdom was attacked by <enemy>, you need to <goal>. Because the gun shoots your soulmate's soul, you can, at any time, exchange your position and velocity for the projectile's. Can you push this ability to its limits? Will you beat this platformer?

Controls explained ingame.

Written in Python, using pygame. You can run this on Linux (or any other OS) if you have Python and pygame installed. (I would love to cxfreeze this project, but there's a bug that prevents me from doing that, it seems.)

You're not missing out on an story, there really is none :)

Unfortunately, I can't make a web player for technical reasons. However, if you have python and pygame installed, I am 99% sure you can just run this as-is on Mac (download the source package and run

Pretty interesting take on the swapping mechanic! I'd suggest trying to package it in an executable if possible. I'm not always keen on running .bats from the internet haha :D

The controls are a bit wonky, I couldn't really jump anywhere. The idea is solid, just needs some polish. :)

Good idea, nice implementation. Controls could use some work, but it's a solid puzzle platformer, nice :)

Nice, I wish the movement acceleration value was less though

Really interesting idea! Just wish the controls where better and it took me quite a while to get the velocity swap mechanic.

Great mechanics and idea! Just thought the controls are a bit stiff. Maybe the levels could have some music too!

I enjoyed the mechanic of switching position + velocity with the cloud

Cool idea, but unfortunately I think there's a framerate issue with the physics. I keep falling through the platform on the second level. My computer is pretty slow, so I think the timestep is too large. I may try to tweak it myself at some point. Overall the controls feel a bit stiff, but it's hard to really nail platforming during LD.

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.
