ATTENTION: The terrain generation feature will be extremely slow if you don't turn on turbo mode. For those who don't know, press the green flag while holding shift to enable it. This uses arrow keys to move around, space to dig, E to place, and if you wiggle enough you can escape the storm's grasp. Particles will be updated.
Just a terrain generation experiment. Arrow keys to move, space to mine. Physics are a little difficult, because I have to do "if touching color ____"
