Frantic Flea is a 2D platformer released in 1996 exclusively for the SNES. It was developed by Haus Teknikka and remains their only published game.
The goal of the game is to scale each stage looking for smaller fleas, who then follow behind the protagonist once tagged. Once a certain number of fleas have been found, as indicated by the percentage given at the intro to the level, the exit becomes active and the player can move onto the next level. They also earn a bonus for finding more fleas than the required total.
Fleas are regularly picked up and removed by enemies, who can also stun the protagonist and cause all the fleas following them to disperse. However, fleas constantly respawn throughout the level, so it's simply a matter of rounding them up again. The player can take a certain number of hits before losing a life. After losing all lives the game is over and the player must start over back at the beginning.
