Hi again, thanks for responding! In my previous attempts he DID growl and shake before getting stuck. I tried it again after restarting my Chromebook, and this time Stan went all the way through the doorway but the game still froze afterwards. Sorry for bothering you about this!

Could you try a different resolution (settings->resolution), just for this scene? I think 720 should hopefully still fit on a chromebook screen. I have no idea why this would work, but apparently someone running windows32 who encountered the same problem managed to fix it this way. If not, I'll take a look at the logic and see if I can tighten it up in the evening!
