I really liked this game, it's clever and super short. Using the SHIFT button to change the stage around to reach the door was fun puzzle solving even though it was incredible easy. The music sucks though, it's some weird buzzing sounds that loops every 30 seconds. I just muted it and played Shibuya Underpass in the background (https://youtu.be/Z4-dBtKcKl4), it fits the game surprisingly well.
