I can't able to create the game account
Thanks for trying it, and for letting me know! There's a problem with the confirmation emails for new accounts on the website, so sign-ups aren't going through right now. I'm fixing it.
In the meantime, you don't need an account to play here on itch. Just press "Play on this device" and your progress saves in your browser. Accounts are only for cloud saves that follow you between devices.
If you saw an error message when you tried to sign up, could you tell me what it said? It'll help me make sure it's properly fixed.
