I've tested the game out on my end and it works fine on full screen and on the jam page. I don't know what's causing it, maybe you accidentally unfocused the game by accident? But I've tested that as well and you shouldn't be able to move at all if that happens, so I'm just confused.

EDIT: tried again, only the first items didn't worked for me, but everything else did work, i was able to now play the game, very hard BTW! thanks for responing though, i can see lots of hard work went into this, i really wanted to like this game, but we only had limited time with it, love to see what you add afterwards
