The intention of this game is known right from the start screen, you got us in the groove.
The timing of the attacks fuses very nicely with the music. Smart choice to make the multi-bullet attack land on the 1 beat, it packs a punch. The drum fills in between sections, especially in the jungle level, were great for maintaining the pace throughout the game.
Really nice work on the art, I appreciate how themed each section is. Fantastic work on this!
