One of my projects from school.
The assignment was to make an game with movement in two directions, jumping, a win and lose condition, and background music and sounds.
The clipping through the floor was acceptable for the class because we don't learn how to stop that from happening until Scripting II which I won't be taking until a couple terms from now. Simple remedy: when you're stuck, jump once to get free.

So Vriska lost her Fluorite Octet in the Land of Quartz and Melody, and she's gotta use her spidery jumping abilities to get them back without falling to her doom (to Terezi's amusement).
Move with the A and D keys, jump with Spacebar.
