An outstanding expression of Llamasoft's ideas. A game of high-velocity puzzles, signs, geometry, and psychedelia that often turns into vibes-based navigation and tests of nerve. The game's speed, depth, and effects are intense in VR while still being readable flat. A few levels towards the end buckle under their own weight in that their mechanics don't quite mesh with how the game is otherwise played, but the finale makes up for it. Level 50, that very last one, is a glorious send-off.
