This is a test for the (At the time) new Interactive Cube feature in the DIESEL Engine. Use WASD to move, SPACE to jump, Shift to sneak, and W+W to sprint. Get to the green cube to win. Yellow is bouncy, magenta is a teleporter, and I'll leave you to figure out what cyan and red do. Have fun!
You move slower in antigravity, and unless you're jumping, the opposite direction of the key you press. Make sure to find the easter egg!
