full-screen doesn’t actually full-screen the game (at least for me) it just makes a new tab where the game takes up the same set of screen-space … which is cropped to where the “turns remaining” indicator and the “retry” button are invisible and unusable!!
after going into “inspect element” and making things bigger manually, it’s much more playable :3 you might try going into the game settings here on itch and making it default to something bigger (or at least square)
after that, i did go and beat it. it’s a nice little puzzle, and i felt the number of levels was appropriate, thank you!
