This is a very nice game, hard, just the way I like it. I didn't finish because of the moving OVNI, but it was very entertaining, it's rather simple, I would like to see something with these mechanics in a more elaborate storyline and settings.
Pros: Hard, good character movement, not Impossible, nice atmosphere.
Cons: Simple storyline, repetitive, overall more valuable as the mechanics of a game than a game itself,
