Hey 👋 I just updated the game, so now things are configureable (and I solved a few bugs while I was there)

Regarding VSync; I've exposed the setting, but it seems like vsync is off already?
We do funky things with framerate (by design) so that might interfere with the setup, and there isn't much we can do about that. But you can try and apply the vsync setting.
