The spritework was fantastic! I thought "basically everything has a countdown timer" was a cool pitch, but in practice the enemies dying and bricks breaking in one bullet basically meant none of them ever had time to count down, so really it was only the blocks you stood on and the final boss (who was a cool little bullet-hell challenge, to be fair). I wished the enemies were a little tougher, and/or if the blocks you shot through needed to be shot the number of times that their number was with walls of 9's or something, to keep you in range of enemies and make it a little more challenging. Or just longer levels, perhaps. Basically boils down to "I had fun and wanted more of it/it to last longer". Good job overall!
