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

Amy and the Magic Hammer

by duck - Jam Entry

My first Ludum Dare game! Short and simple, but... done, at least!

Running into enemies hurts them and you, shrinking you. If you shrink too small, you die. Hit yourself with the hammer to power up - but don't hit the enemies, or it will power them up. New enemies keep spawning unless you clear all existing enemies from the screen. Then you win.

It's an executable .jar, should run on Windows/Linux/Mac I'm assuming!

Programming: Java + LibGDX
Music: Bosca Ceoil (but done before the jam started)
Audio: Bfxr
Graphics: Photoshop CS2

Interesting use of the theme. It was quite hard though, it seemed to just get to a point where they were spawning faster than I can hit myself with the hammer to kill them.

Indeed quite simple, but congratulations on your first LD entry nonetheless.

Restarted the game a few times by closing it before I realized you could restart with control :P. At first I just stood in a corner whacking myself in the head with the hammer, but then I realized I had to act quickly or the enemies would soon take over.

Thanks for the comments! It is a bit hard, as nassi says the key is to be quick - if you kill as many of the initial enemies as possible before getting overwhelmed, you should be able to keep them under control. I thought about adding difficulty settings but ran out of time in the end :)

Red_Fan: yep, I'm trying to pass off my horrible mess of source code as 'programming' ;)

haha, crazy game :p damn, I let Amy die a lot. Need to hit her head more and more. Oh, and it worked without problems on Linux ;)

Ahh poor Amy, always dying :( Good to know it worked on Linux, thanks for letting me know!

I really liked the pixel art and the overall retro style! :) And actually, it's kind of a hard game.
Thanks for being cross-platform! (Linux user here.)

You really do have to get ahead early! My first go I got overwhelmed and ended up facing the wall and pummeling myself as the monsters ran into my back, which it turns out is not an effective strategy. Anyway, congrats on your first 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.
