Review by David Welbourn (originally posted at Baf's Guide)
A short pleasant game where you visualize yourself in a peaceful wooded area. Your surroundings are initially sparse, but as you interact with them, they gain detail, and new items and options appear. The few puzzles in the game are simple and optional; they're not meant to be challenging. The tone is tranquil throughout. A relaxing diversion.
