Love this game!! For me the mouse bug appears to be fixed when I went into fullscreen. The controls were a bit finicky at first, but once I got the hang of them they became fairly intuitive. My only other suggestion would be to make Day 1 a bit easier, so players can get the hang of the controls without failing several times first. But overall an awesome game :D
(btw you can set itch to always play the iframe in fullscreen in the game settings, under embed options!)
