Shütshimi is a randomized shoot'em up about a muscle-bound fish with memory problems defending the seven seas. Armed with your trusty bullet-morphing shotgun, defeat or navigate through waves of enemies and collect powerups as you battle your way through each of the game's bosses. But there's a catch (there's always a catch): you've been cursed with an incredibly short attention span. Combat waves and upgrade cycles only last 10 seconds a piece, so you'd better act fast!
