Same issue here. F5 or Ctl-F5 won’t help, all other games load fine. Running Chrome under Win7. What’s strange is that it did load up correctly two days ago, I’ve played through a dozen levels without pb.
I think there was a Windows update recently, that may have something to do with it.
The game loads up correctly on newgrounds. Can’t think of a single reason why it should work there and not here.
