Nice job! To improve it, there's this strange glitching when looking around where it jumps to a random point, it's sort of disorienting and makes it hard to play. If you don't think you're aware of the bug I may check if it was some one-off thing or if it's something maybe only affecting me. Other than that great job on this game!
(I think I recently found out after seeing this in a few more games, that it's because of no cursor lock and if having more than one monitor, which I just found could be tricky to make, so I may try to just keep the cursor in the game area)
