Flatformer in a box

This is a game where you place platforms. Click the colored squares to change the selection. Different colors do different things, black acts like a spring, grey acts like a standard platform, brown acts like a ladder, light blue teleports you to the top of the game, blue/yellow teleport you to the warp points of the opposite color which is at the location of the most recently placed pixel of that color.

WASD or arrow keys to move.
