Congrats on getting this in on time. I see you had 8 seconds left before the deadline!
Once the game started I immediately got vibes of old 3D maze games I use to play on Win95. It's kind of an untouched game type/aesthetic and it was a pleasant throwback to see it here.
Really dug the music. It adds a lot to the experience. If I'm being honest though there isn't a lot to stick your teeth into here. I never had any idea of what I was doing. When I initially ran into the blobs I couldn't move and died. Running into them again I madly clicked and hit space bar and that seemed to have an effect. I did manage to complete the game, so kudos for managing that.
Some things to work out:
Controls: arrow keys + mouse look is kind of awkward. WASD feels more naturally and is the standard.
Communication: Nothing in the game has a reaction or effect besides doors when you interact with them. Having audio or visual cues would have gone a long way to help communicate what was going on.
Pacing: There doesn't seem to be much of an ebb and flow to room layouts. Every room is rough the same rectangle and size.
Props for using Godot, doing everything from scratch and getting the game in on time.
