Thanks a ton for the feedback, sorry about those bugs, thanks for finding those.
Hmm the “Escape” menu not working is strange. On my end I’m able to use the mouse/arrow keys to select options in the pause menu and highlight them.
When you press “escape” and then hover an option, does it get highlighted? Similarly, if you press “escape” and then press “up” or “down” a few times (without moving the mouse), do any of the options get highlighted? If not then that’s probably a bug, sorry about that!
