Space to jump (or flop) and try to avoid the pipes. You don't really have to read this description Right after posting this I was wondering when I was going to put in a mobile friendly update and I thought it would be a little hard (Because of the stuff in the game) but it actually wasn't that hard so I just did it.
I copied my older "Flappy Bird" game and made it into a "Floppy Fish" game. (It actually was kind of hard to do because of a lot of stuff that will take to long to explain.) Sorry that it's so hard.
