Nice game, fun to play! I wasn't able to claim the tokens (it connects to metamask but then the screen just goes grey and gets stuck there) but maybe it's my browser.
Thank you so much for your feedback!!! for claiming the tokens you should have some test CKB tokens already in your account for gas fees. you can follow the how to install section of the game, it's already mentioned there. I think I should pop a message and tell the user about this
