Only really worth playing if you're playing it through The Basement Collection. That is, if you're trying to unlock AVGM. Other than that, it's just a really average, artsy-kinda game. Not necessarily a bad game, though.
Good, but, mostly because of its brevity, had a lot of missed potential. Oh, well. What did I expect from a tech demo? I'll give you a hint: perfection is not a correct answer.
