Oh I think I didn't collect any zeroes. I was collecting randomly just to see if and when do I get a game over screen.

Ah yes, there is not any gameover at all at the moment. Although I've considered adding some enemy fish at some point and maybe something more negative if the player tries to divide by 0. Currently just makes a sound for that.
I will be adding a save mechanic into the game once we can edit the games. That way you can keep aiming for the bigger numbers.
