Pretty fun. A little basic but alright. I couldn't tell the difference between the bullet types other than the shape. Is it just damage? Also, if it is, what's stopping the player from just rerolling repeatedly until they get the number they want? Could use a little bit more feedback as to what's happening in game, like sound effects. I saw a purple hat with an arrow next to it flash over me and had no idea what it meant, but I interpreted it as a good thing, maybe a level-up? This is a cool idea, but maybe you could expand it to have the bullets have different attack patterns, like maybe one's a shotgun, one sets enemies on fire, one shoots a piercing beam, one explodes, stuff like that. Artstyle's very nice, overall good game.
