CATapult (Alluysl)

Sorry for the blackboxing, I  couldn't do it in the available time.

Also that's not a goat, that's my attempt at making a cat.

Arrows and text are non-interactible, they aren't platforms.

Some platforms are climbable (you can jump while hugging the side and you can hang from said side).

Controls:

WASD  or directional arrows  to move, space does what W and the up arrow  do: make you jump. The down command isn't necessary in the single level I made (it's used to go  down climbable surfaces). Escape quits the game.

Goal: reaching the "GJ!" text

Momentum:

When building momentum (by walking   into a wall or jumping into a  ceiling), you may need a bit of time (less than 2s anyway) to get to the maximum speed. Stopping to move or turning around cancels the  lateral momentum and hitting the ground doesn't preserve the boosted jump.

Skipping:

When going fast against an obstacle but being blocked, you can skip  the obstacle to a position further on the trajectory you'd have taken if you weren't blocked. This is also what initiates higher momentums.
