That's not good. Can you tell me which version were you using?
the web version.only happened after like level 11 or 12.screen sudeenly totally blank from a certain point on, no gears or pendulums anymore.as I flew further to the right, despite the blank everything,, at some point I got the error message
Okay, I'm going to fix this in the future. You didn't miss much; It wraps back to level 1 and shows credits. Thank you for playing!
