A good game with a decent amount of difficulty. It takes a bit to get a handle on the controls but you can start moving pretty well once you get there. I think giving the first few levels a bit more of a tutorial style focus would be helpful in easing the player into the movement of the game without having to reduce the overall difficulty of the game. Besides that when I tried to corner some shots I was a bit surprised seeing them hit the walls so maybe shrinking the collision hit box that checks for walls on the bullets. Outside of that I think the level design was smart, the visuals and sound were nice, and the game expands upon itself in a smart way leading the player to more interesting situations as the game progresses
