Visually speaking, this game is very unique. The field of view and massive walls do a good job of making the player feel very small. I like games that make me feel small.
There's a lot of gameplay ideas here that I can see - using your hands, sprinting, sliding, jumping. The tutorial had me prepared to do some platforming, but I recall mostly walking. You do have to use some of them to complete the game, so there's that.
This game left me with a feeling that I can't quite describe. Glad I played it though. Good work.
