PufferFish Survival (Fish Fest Game Jam)

I made this game for the "Fish Fest" game jam.  
I spent 4 days making the code and dubious pixel arts.  
It's a very simple survival game about a pufferfish who has to shoot red slimes.  
Maybe I'll add sounds and other things to the game if I have time.  
Hope you like!
