Aside from some confusion about where you start on the map and some collisions the game didn't warn me about until I had already crashed, this game is really solid and I had a blast getting through it! Even though your only real environment is the inside of the sub, it really does feel like you're immersed in an alien moon from the atmosphere and the little glimpses you get through the camera. I wish the final scare was as good as some of the other anomalies you get to see, it's a bit lame in comparison.
