W to move forward, S to move backward. A and D to move from side to side. Up/down arrow keys to move up and down. Right/left arrow keys rotate the camera. Any advice (not requests, advice) in the comments would be appreciated!
v1.8: Attempted to fix the buggy rotation system. It is still a bit broken, so I left a camera angle slider so you can still see the whole scene. You will only see one triangle at first, but rotating the camera or moving backward will reveal more. The biggest error at the moment is that turning away from an object increases its z coordinate instead of decreasing it.
