There's controversy surrounding this game of whether it's actually a game, or a non-game. Overall, the reviews are positive. I thought it looked interesting, so I bought it direct, for $10, which provided a steam key, as well as a DRM-free download.
Anyways, the graphics are terrible. It's early 80s-retro, big-block pixels. All you can do is look, and move around. You start off on the coast of a randomly-generated island, and you are free to wander it. Clouds may roll in, darken the sky, and rain will fall. Pixelated frogs will hop away melodiously. You'll see the sky turn red as the sun sets. It's beautiful. The soundtrack is very suited towards this dream-like existence.
You'll either hate it, or be enraptured by it. I like this game a lot. I can see a future for these types of games with higher detailed graphics.
