FeelsAmazingMan, it is a 2D to 3D platform game.
But it doesn't limit the direction of rotation, I can touch yellow block without moving.
Great concept and music.
Yeah, it's kinda broken without some constraints, FeelsBadMan.
It was originally designed with the concept "Only One Focal Length" which can only move the projection plane back and forth, but we want to add more freedom to the player, and it's very satisfying watching the 2d projection moving around.
