NOTE: Because of the Theme tie, we allowed everyone to pick either Theme. Using both was optional. To keep things simple, there will still only be one Theme category. Every category in Ludum Dare voting is an opinion, so you’re welcome to rate them as you see fit. But we encourage you to be fair in your scores to people that chose only one Theme, and not both.
ALSO: Itch.io has an experimental game downloader over here. You may find it useful.


Radioactive Bubble Boy is platformer that includes both themes:
Two buttons (left and right arrows) to move and jump.
Collect bubbles to grow yours large enough to fit your significant other with you.
Some mechanical tips for those having difficulties with the controls:
-Jumping from ground always goes to direction you press first.
-Jumping from ground doesn't give you air-control.
-Walking off ledge without jumping or touching even briefly a ledge when wall jumping gives air-control. Same if you fall from wall without pressing any button or holding the button towards the wall and not releasing it.
Game Logic does this all with state system. If you intentionally jump/walljump( or press towards the wall to release from wall) your character is set to "jumping" where you cannot change your velocity in mid air. When you touch ground or fall from ledge/wall you are set to "idle" state where you can move to "moving" state.
In testing I've managed to get every "GREEN" thing at least once. But my best score is getting 10 of them without dying. Leave a comment if you can beat that. :3
Would love to see someone reaching the end screen. ^^

cool game, the face's scared me, thinking it was demonic, thing but then i realised its heart in eyes. good job
Neat concept but hard to go the direction you wanted to after you jumped!
Nice game, I think there needed to be a bit more tweaking with the movement of Bubble Boy. Well done!
+ Good graphics and sound.
+ Good platformer gameplay.
+ Funny death message.
- Hard controls
Bubble Boy's expressions are really cute, and the notes were funny.
Conceptually good, but I think the controls could use some work.
Controls are really difficult to learn, a tutorial section to learn it would have been great. Has potential
This was a very clever movement mechanic. Its cool how the player can navigate through the entire maze using only 2 buttons!
My only complaints would be that the controls were tricky to use sometimes, and that there was a lot of 1 block wide vertical paths which the player needed to go up to get to the next area. I found that these were hard to get the player to wall jump up.
Interesting game though.
fiddly controls... I like how you always are called "sir" ^^
Sound gets a little repetitive, but controls are easy to get used to, great game ^w^!
Cool use of the theme and overall a good idea but the controls are hard to get used to and can result in frustrating deaths.
Great game and good use of the themes!
The controls are a bit dificult, but that's challenging :)
Music was really nice and the little faces were cute, but I couldn't understand the control scheme at all - it seemed really inconsistent. It seems like a cool game but I can't really play it :(
I like the mimic of the character and the messages you get when collecting stuff and on game over. Jumping is quite difficult though.
Silly error on my part, with mimic I meant facial expression.
Cool game! I like the sprite design and the music is good, but the controls are a bit hard to use.
Fun animations and UI. I liked the audio track, but it was a bit short. Would have appreciated more intuitive controls and level design.
Great game I loved your controls and mechanics. I found the gameplay very fun and the random generation makes the game have high replay value. I also thought the subtle face changes were a nice touch. Overall great entry good job.
by the way in response to your comment on my game. It fits the theme of "Two Buttons" by having the "Left Click" and "Right Click" being the two buttons. We also didn't apply the second theme grow, although we wanted to we couldn't figure it out without the animations looking off. Luckily the rules say we can use either/or theme so we chose the former.
You had buttons in that game? I beat it without knowing there was any other controls than mouse O_O
This was an interessting entry. the controls were hard, yet easy at the same time. the platforming was difficult, but not impossible. i liked the challenge!
would have been much better without the left+right = jump control
The controls took some time to get use to. But I did like the game, and I think you could add to this and make a solid IOS/Android game.
Controls are actually great once you learn them. Good music and pretty nice graphics as well. Great job.

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 (http://mysite.com/mygame.zip) 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.
Very hard to get used to the controls.
