Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

That should restrict your mouse cursor for a first person game.

Really creepy sense of atmosphere! Felt on edge the whole time I was playing! Also a very cool idea to mix 2D and 3D like you did. Unfortunately I have a bad case of the stupid and am very bad at these puzzler style escape room games so I didn't get very far lol. Nice job!

I see a ton of potential here, I really like the idea of having to manage a large facility while fending off enemies. But I got stuck due to the mouse cursor not locking correctly and couldn't navigate effectively. But the tamagotchi you get is cute and the overall idea has a lot of potential.

Despite the issues, nice work.

Cool concept for a game, I like that you just drop out of a pipe at the beginning of the game. There was no audio present at the beginning of the game though, so I eventually got stuck and didn't know what to do.
