Maybe change the mechanics a little so you're digging into the ground and some of the tunnels you dig fill back up with random stone or ore when you get back to the surface?
Lasership 1.1 is now published! I've re-written the code and added ship customization as well as new parts and a better looking shield. I've put most of the original things back in except for health repair. I might put that back. Multiplayer and multicolors coming soon!

Thanks, but I figured it out anyways. Now I just need to figure out how to do sprite customization. I tried using sprites and variables, but they don't want to mix.
