I like the visual style.
The mouse doesn’t get captured by the game properly on my system, so playing it was a bit tough (it drew a cursor on top, and if I click when it’s outside the game it would lose focus).
The lean doesn’t do much because it rotates around the camera rather than around some pivot (like where the character’s hips would be).
I’m not sure how well the game fits the “joined together” theme, but I guess I could kind of see it if the “joining” of the corridors was somehow witnessed by the player as it was happening, or if it was somehow a part of the gameplay.
