It's cool to see a 3D game! For something made in 2 days, that's pretty impressive 🙂 There are some cool mechanics like the locked doors you can open by pressing the correct button. What you have can be an excellent basis for an exploration game, with NPCs and different locations to explore.
As it is right now, the enemies are unforgiving, resetting your position and number of keys is a bit harsh. Besides that, great work!
