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.

Bubbles & Slugs

by Chaoslab - Jam Entry

Bubbles & Slugs an Abstract Arcade Game.

Some one was mean to you at school so you have decided to use your Slug Gun to destroy their Lettuce Garden.

Left Mouse (keep the button down instead of clicking)
- Click on Bubble to collect it
- Click on Slug to collect it
- Click Helpers to spawn Bubbles and Slugs

Right Mouse
- Click on a Chicken trap it any Bubbles you have.
- Click on a trapped Chicken will make the bubble stronger (and cost a bubble).
- Click on Left / Right Edge (Highlights Green) to Fire Slugs you have.

Once all the Lettuce has spawned and has been eaten you will progress to the next level.

NOTE: This is a JAVA Application so download the current version and install it from Oracles site if you need too.

General idea is to collect Slugs and Bubbles while waiting for Lettuce to spawn. Once the Lettuce has spawned you trap the Chickens and spawn your Slugs accordingly (till all the Lettuce has been eaten).

If you run out of Slugs or Bubbles the helpers are there to get more.

It is a small entry (that took a while to get momentum). Didn't make a start screen so the game just starts at Level #1.

Made all the Music, Pixel Art, and Code (minus libs).

Enjoy your unconventional weapons Bubbles and Slugs! :-)

The Bugs are so bad it will not even run except in dev mode on my machine. Will post when a working version is available.

Game is now loading and running so it can be downloaded and played, but...

Bad Bug in level completion code that needs to be fixed so the first level is not completable.

You can use command line args to see the 8 levels, example:
java ld level:3

Getting back to bug fixing.

I tried running it from the command line like you said but I just got a few file does not exist errors and a few others, I think its because I don't have a c:/_resource directory or a dev.bld file in the install directory

Thanks for that. So Mac OS is out till I get a fix in, damn. BUG 006: added.

What system are you using? (try the run_game.bat file if using windows).
Both the dev.bld and debug.bld should not be there and are not required (just empty flag files anyway)

Creating a debug.bld file will make the game print debug information.

Chaoslab says ...
Apr 22, 2015 @ 3:10am

Okay update guys! Found problem with loading files and fixed it and updated the .zip so please try again.

ianb96 says ...
Apr 22, 2015 @ 3:21am

I am on Windows 8 64 bit, and when I run the run_game.bat file a window pops up with a command prompt, then both immediately close. when I add the debug.bld file nothing changes with the run_game.bat, but the running java ld from the command line is the same as ProjectX593's output but with some DEBUG FILE lines for sprite_list anim_list, gmae_logo, and so on. the line before the second spr_imageio file does not exist? error says Gameobjects.init

The latest version works!

Chaoslab says ...
Apr 22, 2015 @ 3:27am

Thanks! Hope you enjoy it! Completed it on delay:0 before, was not easy. Must fix the none looping music bug (app running in the first place was more important though and luckily not even code just some .xml).

Trippy. A bit hard to understand how it works at first!

Apr 22, 2015 @ 3:36am

Took me a while to understand a bit of what I was trying to accomplish and I had collected dozens of bubbles and lost all my slugs. Eventually finished the first level though. Maybe a super-basic intro level would be helpful?

Cool concept, I really liked the music. Had to open the ogg file in itunes since I'm on a mac so I could here it while I played. I'm glad I read the instructions first, I'm not sure I would've figured out what to do on my own. Fun game, nicely done :)

No bugs here! Great music. I never really understood the game but had enough fun watching the slugs move around and popping bubbles. Good job!

Apr 26, 2015 @ 6:08am

At first, I was quite lost on how to play the game with so many things moving around. After reading your description, the objective was clearer. I've realized there is no way to actually lose, which is alright since there are so much things moving around. Very interesting concept. Nice work!

Chaoslab says ...
Apr 28, 2015 @ 6:21am

Thanks! yeah there is no way to loose but you do have to play the game to win the level. The chickens eat any free ranging slugs pretty quickly and also get "energized" after eating a certain amount of slugs making them even more challenging. :-)

Chaoslab says ...
Apr 28, 2015 @ 6:27am

Thanks man, that is what I was aiming for.

I do want to make a more fuller version at some point so will definitely add something like that.

Thanks, been making music for a few years now, so much fun to do.

Thanks. That is what I was hoping for! :-)


Thanks. Did my best to make it feel old school. Coded "Sirius 7" on the Amiga back in the day. :-)

I found quite interesting the idea of using bubbles and chickens, but found it a little confusing to play and not fully understood the goal of the game. the fact that they used simple blocks for the construction of the scenario is a total merit of creativity. Congratulations

Even after reading the instructions, I'm still confused over what is going on on the screen. I made it to level 4 somehow... Cool music though.

Very energetic/frantic game. Graphics are somewhat confusing, but I did score by clicking on bubbles.

Chaoslab says ...
May 7, 2015 @ 8:17pm

Thanks. I am planning to make a better version (20 - 30 Levels and Custom Levels).

The game is pretty fast (even the slow version). The idea is to collect slugs (save them up for the last few levels ), collect bubbles and trap chickens (do not click! keep both buttons down - see below). You collect more slugs via the left side helper while waiting for the lettuce to spawn. Once all the lettuce has spawned you trap chickens then use the slug helper to release a burst of slugs to get the lettuce. Difficult lettuce can be hit by right mouse clicking the sides after it lights up green, then any right mouse click launches slugs you have, careful though as you use them quickly. The launched slugs are very very fast and cover allot of screen space. Then you keep the chickens trapped by right mouse (down) on them to strengthen the bubble and they do not escape.

That is the long of it. :-)

It is better to keep both of the mouse buttons down than click. Then you pick up slugs / bubbles and also trap chickens at the same time (but do not go to the side edges of the screen and accidentally fire slugs).

Thanks guys. Have a draft Retrospective that will publish today.

I don't understand it, but it's surreal as hell. Looks awesome.

May 7, 2015 @ 9:26pm

A bit too much going on at once. Perhaps a tutorial level explaining the effects of each of your abilities would help. Felt like I was winning by just clicking at random.

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.
