Thanks for your in-depth feedback! I agree that using the mouse we could simplify the controls a lot… gotta refresh my matrix math but it’d be worth it. Sorry about the freeze! It’s a custom engine and some parts are a bit rough around the edges, but freezing was not meant to be a feature! If it happens again, I would really appreciate if you can get a stack trace (just expand the error message in the browser console). This will allow me to find the code path that’s crashing and patch it up. :)
