While I can see where you tried to touch on some pretty deep and complex themes here, I find the game in general to be lacking both on a thoughtful level and on an interest level. I think the themes you tried to convey are simply too untouchable for the setting you put them in. This game, I feel, does not explore what your description claims it is made to explore. Instead, it merely glosses over them, almost just kissing them as it passes by, unscathed. There could have been more here.. something more than a commentary on the banality of some "art" games, on the metaphysical exploration that many indie games slog through these days. You cite inspiration such as Sartre and Kafka, but I cannot see that inspiration here. Your quest to simplify the ideas of the writing you mention has diluted them to the point where they are neither effective themes or useful game elements.
I wanted to like this game, but it seems more like a parody or a spoof than anything else. I'll give you 2.5 stars. The programming and art style are good, but not great. The overall theme is tired and simplistic, saying everything while saying nothing at all. The three-act style is effective and strong, and does well to keep the player's interest, despite disappointing gameplay.
Thanks for making the game! I know my opinion of it isn't terribly positive, but I appreciate the work you put into it.
