i tried to run the x86.zip file through the emulator joiplay and it asked for a password. do you know what the password is?
The game is not playable through that app and the zip you downloaded is probably from a third party site, since I didn't upload any.About your issue though, I'm afraid I really don't have a clue what could be causing that. I'm leaning towards it just doesn't work on a chromebook.
