Nice little game.
Would of been nice to have a little more graphics assets to put on the walls and background.
The physics and mechanics are pretty well done but i feel like it would be way more ejoyable if you could either stop time in the air to aim or be able to stall on the wallto aim. Right now aiming while being in the air doesn't feel good at all.
Otherwise the game is pretty simple but effective, hope this can help you improve the game :)
