Tap to move, with the grace of a fish out of water, and help Floppy back to the ocean!
In order to move, you must tap the screen. This sends out a bubble projectile, and recoils the fish in the opposite direction. Simultaneously, the fish also generates rotational momentum. If the fish faces right, it will spin anti-clockwise, and vice versa. You can jump both on the ground and in mid-air. In terms of obstacles, the main concern is spikes, which kill the fish upon impact.
