Sorry to hear that. What GPU were you using? I haven't tried it on anything below a GTX1060 with 6GB of VRAM. The controls issue could be related. I've tried it on a few computers and the controls consistently worked.
Well, I just went to double check what the nvidia card on this system is and it looks like the game is actually falling back to my integrated intel gpu, which is probably why it's struggling so much. The dual gpu stuff on this system _was_working but I guess it's broken again. I'll try the game again if I can actually get the nvidia card working.
