This game, I love pixel styled games but this one I honestly didn't like too much. First of all, how slow you walk really got on my nerves, you could have made that a bit faster. Second of all, just the way you talk makes it very hoaky. If something "odd" happens you seem to blow it out of proportion and freak out. I feel like a more rational response would have made this game more "eerie" .
Also, there isn't much interaction in the game, little controls and most all you do is walk to and from each day until the climax, no challenge.
The achievements, I feel as if they're much too easy to obtain, all you really have to do is follow the storyline as expected and you get the achievements, there's no actual challenge to them.
I have to admit though, as the game went on it had an increasingly eerie effect on me. The music was a very good choice, it did define what being on the moon would really be like. Quiet, lonely, static noise sort of feel. So that was a good point. The story overall was great, yes it was a bit cliche but it was a good story but I don't think you took ahold of that aspect completely. This game could have turned out to be a very scary, interactive game.
Also, this game very much reminded me of a movie called 2001 Space Odyssey, very strange.
But an overall rating: It could have been much better, very predictable, eerie at times, little interactivity, and slow movement. 2 stars.
(Sorry if this was a bit harsh, I don't intend to be an asshole.)
