Good work, cool visuals. The "fit-in" idea itself is very cool and at the same time simply (which is good) executed. The game's message is clear.
It's a bit awkward, though, holding down the keys to switch between modes. I don't think the placement is ideal. (Right next to WASD). Hard to sprint, move and hold "fit in" mode at the same time. I wish it could be toggled.
