I enjoyed this, could use a little more polish though.
One big thing I wish it had was a setting for mouse sensitivity, I felt like I was looking very slowly.
The only door I didn't really like was the earth one just because it felt like it took so long to get to it.
Overall I think it's a cool concept and it was exciting wanting to see what was behind the next door.
I did find a couple bugs:
One was that when you press p to view the leaderboard, it scrolled so slowly that I couldn't ever get to the next person.
The other was that after finishing the game, the wheel still said 9/10 instead of 10/10.
