Thank you for taking time out to play it.
That's a super interesting bug with the mouse. I'll have to check it out. It's most likely I bugged it out when I make the mouse cursor visible in the menus (Just thinking out loud). Not sure about the door but I'm curious about what happened. I genuinely like it when people find bugs. It's always fun to try and figure them out lol.
But thank you so much for playing it. It was extremely fun to make and it's nice to know some people have actually tried it out.
