Definitely a pleasurable game.
Not considering the fact that this is your first game and coding of mechanics and script, it's splendid. Truly great, most of all the atmosphere and flawless visuals, very much so minimal, but effective. I would add a different ending or couple of endings, at least what I got was little raw, but it's just a nitpick.
You should be proud of this game. Amazingly designed and everything looks really neat. Well done.
