Hello! Thanks so much for the bug report and video. Can you tell me more about what (if anything) led to this happening? Was the game otherwise pretty smooth (45-60 FPS) before this?
I might guess that the window lost focus for 10-15 minutes. Something the game engine isn’t good at right now is handling time while the browser is minimized or in the background. I’ve seen this happen with the flashing colors when the game tries to crunch a bunch of missed time. There are some things I can do to improve that in the next build.
