The game looks nice. I like your 2D animations. I also like the mechanics and puzzles, they are indeed interesting and quite clever. I just think you shouldn't have written that in the game description, don't get me wrong, but self-praise is not cool, let others decide whether your mechanics are interesting and puzzles are clever :)

Some sounds would be nice, but there were just 10 days to make a game, and making sounds, or even searching for fitting ones is a time-demanding process and you obviously spent that time on the different parts of the game, which I think paid off.

Overall, very good game, well polished too, for a jam game. Great job!

Really nice puzzle game, managed to complete all the levels although the shot in the upper left section of the last level took us a million tries and it felt very tedious rather than fun. It would also be nice if the explosion effect of the ball wasn't as massive because it makes it harder to see things when it happens and it feels a little excessive. Maybe a simpler but still shiny smaller particles effect would be nice?
All in all everything else worked perfectly fine, the different mechanics were engaging and you introduced them very well. Good job! o/

Really really really interesting mechanics. more a puzzle than a platformer, which I prefer.
I'm so frustrated there is no sound and music though, a game this good needs them.

Also one other thing, I don't think you can fire the ball while the jump animation is in progress, I think you need to go into the animation controller and change the setting so you can fire while you are still jumping. (Something to do with end state that you toggle).

Please keep working on this I'll follow you to check for upgrades.

It's a shame there are no sounds or music because everything else in this game is just so excellent. The game does a perfect job of teaching you how to play without saying anything, and it's fun and responsive and nice to look at. I beat all 13 levels and I almost never stick it out like that in these kind of jam games with puzzles. But this one, I would have continued playing if there were even more levels. Really fun and excellent work.
