WASD - Movement QE - Up and down Arrow keys - Rotation Other than that almost no content. I may make a full game using this method at some point. The biggest issue is actually importing a high resolution map into scratch - Consider this project can do about 4 pixels per centimeter that's a lot of data for a small area! I currently procedurally generate this, but one day I'd like to import a 3D map of a real life place into this project - and possibly make a flight simulator or something like that using this technique.
Since coding in C++ for a few years I've become a lot better at programming in scratch too! This was a project I made in about 5 hours just to test an idea I had for fast 3D on scratch.
