Instant fun and a simple game to pick up and play.
I really like the boss variety here cause you don't know what to expect after a restart with the procedurally generated bosses, it keeps the game fresh.
The one issue i feel is the movement that's a bit too floaty so it makes it a bit harder to precisely pass through some of the tighter gaps.
Other then that its a neat entry and i had a good time i also like the pixel art here.
Good job :)
