It’s not too pretty, but my full game can be found here: ShareMyGame.com by GameDev.tv
I left the cheats turned on (N for next level, P for previous level, C for clipping, Z for resetting your X & Y rotation (since sometimes the constraints don’t work right), so feel free to skip around a bit so you can see each of the mechanics I’ve implemented.
Let me know if you’ve got any feedback!
