One reason this could be happening is if you are browsing in a private/incognito tab. Since those do not allow the game to save your progress in the browser.
Hey dude i played in chrome at mobile and the same thing happend the game crashed and im not incognito could be my phone or the browser are broken or something
I'm sorry to hear that. Sadly the game requires access to the localstorage to save and load. I have tested on chrome for android and I couldn't find a way to reproduce the error :(
