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

Portal Miner

by TimBeaudet - Jam Entry

You are a mineral miner of the future, travelling to distant asteroid fields to collect resources. After finding the collection process to be slow with travelling, you've unleashed a weapon; the portal, to collect and process each resource immediately.

The job is still dangerous, so don't collide into the asteroids with your ship!

Good luck and please give us feedback!

NOTE: If you are on Windows missing OpenGL32.dll there is a link to the redistributable in the readme.txt or here:

The game was made by:

Programming: Tim "BlackBird" Beaudet
Art: Sonia "Dizzy" Augier
Audio: Jeremy "Mmango" Bell -

Well done! I really like the art style and the music. The game runs very well, so go TurtleBrains!

I really liked your entry man, Would have been nice if the portal stayed open a while longer to get some of those impossible chains.

I really enjoy these types of games, would be awesome on mobile, and my missus would play it too :D haha

Awesome job *thumbs up*

I like it. One thing I'd suggest is working out the mechanics so when moving your portal gets placed on whatever row you are closest to. I found I would switch rows and then right before I finished switching I'd fail to place a portal in the right spot. Also seemed like row switching could happen faster.
It seems like the map wasn't fully proc-genned or something? Was getting the feeling like everytime I restart I went through the same things.
Music was good, liked the portal sound as well.

Thanks for the feedback, we appreciated it!

The map isn't procedural at all, it started out that way but then I opted for "designed patterns" so that it would always remain playable. The scroll speed does get faster and faster, although probably does so too slow. The first pattern is _always_ the same as a tutorial-ish level. And then it randomizes between the other pattens we got to make. Admittedly we meant to have more patterns, and have them designed better, but we didn't get that far.

Great concept, it'd be cool if the portal stayed open longer so you could build combos. There were a few instances when a gold and a normal rock were on top of each-other and I didn't get the gold because the rock was slightly ahead. Perhaps a secondary goal would be interesting like collecting certain types of materials to craft additions to your ship. Overall, good job.

love the music and i like the concept of the portal placement, i wonder where all those asteriods end up ?!

This game was horrible. Apparently the portal was not even a donut. I really would suggest thinking about your game concept before making the game.

Alright in all honesty I thought the game was awesome. Very interesting idea, especially with all those other rocket & asteroid games. I was surprised to find such a high innovation. Music felt very calming and fit with the game well. Fun to play. Good job! :D

The portal mechanic is pretty cool - I was worried it would be a Portal ripoff heh. The patterns of asteroids were nicely put together too and really fit well with it.

Hey, great game! I ran into a few errors, though. Couldn't reproduce them, so it may just be my machine. Links to screenshots of errors:

Only the 3rd error actually crashed the game, I was able to continue play through the first two.

I still wonder if I could reach 10,000 points, but I settled for stopping at 7600+. :D

I missed being able to move around the screen, but had fun mining in the space using my portal generator ship :).

Marcus, it appears you need to reinstall OpenAL, a link to the redistributable is found in the readme and in the description above. Thanks everyone for leaving the feedback!

I actually installed OpenAL specifically for this game. I wonder what went wrong ...

TimBeaudet says ...
Apr 25, 2015 @ 6:47pm

Maybe there is another issue with TurtleBrains? I did have a crash during development, but reinstalling OpenAL is what fixed it, so I had figured that was vastly outdated or something, it had been a long time since I had updated.

Cool concept man, it's like a defensive SCHMUP. Good work.

If you kept working on it, it would be cool if there were different types of enemies and maybe different kinds of portals to use.

I second what others say about the portal staying longer so combos can be built. Some of the rock layering could also use work, but overall a good entry.

Pretty good game. Felt like I was mostly dodging. I'm wondering if it's possible to take this game concept further. I admit that for me, the current implementation is a bit too simple.

Control-wase, it would have been nice if I tap up, then space very quickly, it would place the portal at the lane I would end up on, rather than the lane I'm currently in.

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.
