I'm honestly surprised you managed to make such a polished game in only 48 hours! The gameplay and the art, effects, sound fit so well together and the replay mechanic is such a fun yet coherent addition to this game.
Kinda reminds me a bit of bullet control minigame in Rayman 3, which I've always loved.
Also, I love how the menu buttons scroll up instead of the bullet indicator. Its a simple thing but really nice role reversal :)
