I got it downloaded (thanks for the help with 7-zip, guys!) and opened it, then played some of the tutorial. When i got the the computer bit, i found out that none of the menu buttons worked, as if their hitboxes were further away, like i would hover my mouse over a random part of the screen and then a little box for the item name would show up. And when i tried to close the game and reopen it, it wouldn't let me.

Try do F11 and change resolution
UPD: nevermind, im dumb, if your keys dont work so that wont fix that. But still, maybe they will have normal hitbox when is not fullscreen.
Also: tip from the game itself
