Thanks for playing yo! I really have to look into SkiFree at this point. Everyone is mentioning it but I've never played it before.
I'm not sure what browser/webview the itch.io app has, but it's sad to hear it doesn't work there though. I think as of now, too, it doesn't work in incognito chrome (especially s an iframe)
But thank you for pointing these out, so that I can fix them for future versions of the game engine!
