Use your mouse pointer to go where the fish is to then collect it's guts I guess. You have ONE minute to do so. Also, maybe try to beat MY high score! (It'll change every time I play and get a higher score than the one in the 'instructions' tab, which is this one.) Developer's (Me) High score: 592 Try to beat it in one go ;)
This game doesn't save. You've been warned.
