This was a pretty solid experience. The controls were a little confusing at first. Took me a minute to realize the "a" and "b" buttons actually referred to a nd b on the keyboard lol There is potential for some real solid puzzles in this game! I played it here:

This is a really well made puzzle game that has puzzles that really make you think about where the cube needs to be, it took me a while in level 2 to figure out how to move the cube so it didn't get destroyed

Great game

This is a great start to a puzzle game! I liked the Baba-is-You-style mechanic where your actions are changeable based on other factors. Great work! I'd be interested to see more levels.

Wow! This is really cool! Like this a lot! 

Very cool mechanics! Wish there were more levels, but it's fine, it was a 48 hour jam after all. If you can, maybe also drop me a rate: Project Marble.

Interesting mechanics! 

Clever mechanics :D! Though, I wish the "laser" sfx were a tad less jarring since its being used so often! Would be fun to see even more clever level-designs w this idea!

Fun puzzle game! Level 4 was challenging. I think a level reset might be useful.

Really clever mechanic, as others said changing the controls to numbers or wasd would be great

The mechanism is kinda fun! Would be great to see if it gets explored more so the levels are more playable.

Gonna echo everyone else here and say that these are some fantastically original mechanics. A lot of fun and a real challenge! The only thing I'd suggest are different controls. A B and C are very easy to keep track of visually but they're kind of far apart on the keyboard, which is a bit uncomfortable if you want to use them in quick succession like on level 2.

Perhaps numbers would be a better choice, since those are all in a row!

Oh also, I got the same fire glitch Waekyben mentioned xD Just a small thing though. Bugs are bound to happen in jams :P 

Well done with this! Best of luck in the jam!

Very original idea, great execution.

(Fire sound got stuck on loop after 4th level)

I love myself some clever mechanics, and these are some clever mechanics. Great example of a simple idea well executed.

I loved this game, even though I didn't finish it. My only problem is that it is a bit hard to spread my fingers out between the A, B, and C keys, I think keys in a row would have worked just as well. Other that that, I think this is a solid game!
