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

Orion's Battle

by w1n5t0n - Compo Entry

This game was made in java with LWJGL (a library that lets java access opengl). The library uses natives (precompiled C code), there are natives for windows, mac, and linux. In theory that game will work on all of these OS's. Windows works fine but in Mac some security settings have to be changed. I'm sorry if the game fails, I'm not very experienced. Also high scores will be saved on disk only in windows, I just didn't have time to implement mac and linux file system support. Also the windows, mac, and linux download links are the same. It's java and so it runs on everything. The natives included are Windows, Mac, and Linux.

If jar doesn't launch correctly try to go into either terminal or cmd and run the command: "java -jar [game path]"

The craft can be controlled by the arrow keys and WASD.
The craft moves by exploding bombs beside it, when a key is pressed a bomb exploeds at the corresponding side. For example, when the down key is pressed a bomb will explode under the craft pushing it up.

Game Idea:
In the game the player controls a craft named orion, this craft has a nuclear propultion system. This means that it uses bombs to move.
One day is space aliens came twards Orion to attack it, to defend it-self Orion has to use it's propultion system to exploed the alien ships.

Game Info:
The game is endless and keeps track of how many alien ships were destroyed. High scores are saved in a file is the game is ran on windows.

I love it, pretty interesting to avoid enemies while trying
to hit them with a bomb that is next to you. However, the game seems to freeze when I press space. Is this supposed to happen?

Regarding the OP saying that on Linux the game is "weird and it sometimes doesn't work"; It's working perfectly fine for me, launched a couple of times.

Hi Jordan, sorry about the bug!. It was a thing i put in so that i could take screen shots and i forgot to take it out.

Works on my Linux perfectly well (Ubuntu 64bit).

Super cool idea! I found it pretty difficult to remember to hit the direction opposite where I wanted to go :p

I'm going to assume that UFO's spawning in all 4 corners on every frame after a while wasn't intended behavior. Or is it? I'm not sure... (Happened after one bomb on Hard, and at about 25 points on Medium.)

Anyway. Killing things with your thrusters. So counter-intuitive yet rewarding. quite the fun idea. Good job!

Thanks for the feed back, it's really nice to see that people like my first ludum dare entry!

Pretty Average Game. Also has some glitches.

Fun idea :)
At first it was difficult for me to get used to movement but when i got it, it was really rewarding.

Fun and good concept. Kept forgetting that the directions were inverted though!

Also, thanks for pointing out the mouse lock issue in my game. I believe I've fixed it now.

The game is fun to play, but i think it is very simple for the time span that we were given to make the games. i think that you could have added a lot more content. BUT it is good GRATS.

Cool little gameplay mechanic, I like how the keys are mapped to thrusters, as opposed to direction.

Is the name a reference to Project ORION?

I liked that the aliens got more and more frequent over time - but they could perhaps try to avoid one another.

w1n5t0n says ...
Apr 21, 2015 @ 1:13am

YES! Someone got the reference! Good job!

Super fun. Despite your bomb explanation, I felt like I was flying around and trying to cook enemies with my engines. A polished version of this would definitely steal a few hours of my life. Good job!

At first I was confused why you pressed a direction to go in the opposite one. Then when I actually read the instructions it all clicked. It is counter intuitive to press in the opposite direction of the enemy to get closer to him, then press towards him to kill him, which moves you away.

Fun and +1 for having a menu! Menus make everything seem polished.

I like the mechanic, but it could definitely benefit from further sound effects and music. The game plays very nicely though. I feel like you put together a solid, if simple, game, well done

Controls take some time to learn, I did not expect that kind of response - but pretty fun. A little jerky, though - could benefit from velocity acceleration over time.

The idea itself is great and well executed, congrats!

Nice idea, hard to get used to the controls though. Ran find on Linux for me (Bodhi 32bit)

Interesting idea! Though it needs to be polished - the enemies have pretty schematic behavior so one can rip that off to own advantage. Cheers!

I like the concept quite a bit. It's innovative and interesting. However, the choice to reverse the controls feels a bit contrived and not very fun, though I understand the physical reasoning.

Apr 29, 2015 @ 6:59pm

Really difficult, as it's kind of counter intuitive to move in the opposite direction of your input.

Great effort for creating the game by yourself in under 48 hours.

Takes some time to get used to the controls but I do like the idea of using your only means of defence to move your ship.

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.
