This should be entitled as "Door Demo", the game itself was interesting to play and it was fun to try to solve the puzzles, not all of them have the subtle hints the other doors do and also if you solve one side and then fail the other it resets them all which was a little bit tedious.
It would of been nice to see a little more gameplay out of it and maybe a little more interactions like if a door was locked it should let you know why you could not access it so the player has a little more direction, aside from that a fun little experience.
