Err... well, how do I put this...?
The title screen is really beautiful. But the game doesn't match the art style it depicts. The gameplay was pretty straightforward to me, but the controls felt a bit clunky and the deflective pallet never really stuck to the angle I wanted it to. On the other hand, I've worked with projectile deflection games before, and I know how much of a pain it can be to set everything up sometimes. That, and I find the concept fits this Jam well.
The music was alright, but there were few visual and sound feedbacks (when I killed an enemy, it literally just disappeared). Maybe working on that game feel would be a good priority ? Good job for that title screen though - it was what drew me in to this page in the first place.
