Shutshimi

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! 

Key features:

• Endless waves, endless fun! 


• Rapid-fire gameplay! The rules change every 10 seconds, so react quickly! 


• 5 different weapons to choose from! 


• Over 40 upgrades to acquire! Combine upgrades with different weapons for interesting combinations! 


• Hats! Over 30 of them! Most hats unlock hidden "Hattributes" which modify gameplay even further! 


• Full keyboard and controller support! Play any way you like, as long as it's either of these two options! 


• You can smoke underwater!? 


• Leaderboards! Compete with friends and foes for the global top score! 


• Local Co-op! Work together or screw each other over when competing for the top score
