Wow! This game is damn hard! But I kind a like it ;D
The given situations are very tight, a lot happens at the same time and you have to react very fast, but actually to memorize and find a solution, kind of which steps the player has to do to beat a level. At the same time you need to get better with the control scheme. The game is like an shoot 'em up bus as a platformer. And then you have this simple mechanic with the bullet, which bounce and have to be collected.
The overall gamedesign is great and it has also a great game feel! Great job here!! Will definitely return later and play it again :)
