Yeah, sorry, but it still doesn't fit completely on the screen, it's awkward. Also, I don't really understand the controls—do you use the mouse or something? (I can't use the mouse for anything, so I'm not really sure how to play.)
Everything is explained on the right of the screen, and i don't get how your window can't fit since i specified the exact size required for Itch. Please send a screenshot of your view.
Right now you play as Player #2 so you are the base on the right, it's the only cell available for now, then you will expand and develop your territory.
