A very cool UFO based metroidvania with a lot of atmosphere that's just a bit short and lacks impact. The game looks great, the eponymous shadow planet has a great look to it with great use of dark silhouettes and vibrant colors for them to contrast against. The twin stick gameplay works reasonably well too, it's light fun moving around, shooting, grabbing or sawing stuff and solving puzzles. The game is pretty short and straight forward, but it's fairly good light fun while it lasts.
