Basically title. Many levels seem to have bugged physics as balls will randomly stop either by slowly decelerating before they're supposed to or sometimes even just stopping on a dime. I've played most of the Zup games and I've run into a couple of weird things like this, but I have usually just concluded that my timing was off or I wasn't understanding the puzzle. In this game, however, it happens very frequently and I keep having to double to check a guide to confirm I AM doing it correctly and the physics are just incredibly buggy. It's happened so often I can't even be bothered to list all of the levels that I've had to force restart the game to get to work properly. I think I'm just venting. Maybe I should be running the game differently? Windowed mode? Different resolution? Idk...
