Juuuuuuuump!!!

Juuuuuuuump!!! is a two-player co-op platformer with a surprising twist: the other player controls your jump. Warning: Friendships may be shattered by playing this game.

Controls:

Player 1: WASD 

Player 2: Arrow keys

Each players jump button causes the OTHER player to jump.

Story:
Your goal is to help the fish brothers get back to the ocean. Unfortunately, they tend to be very lazy and refuse to jump on their own. You have to startle the other fish, causing them to jump upwards to progress through the levels and beat the game.
