This game was weird. It was fun, but it is hard to point out what in particular was fun about it. Perhaps it is the attention to detail, despite the minimalist character of production altogether. The way various protagonists move, is one example. The platforming aspect was surprisingly fluent and precise.
The atmosphere of the game had very dystopian feel to it and it made me ask the question, what is with the protagonist in particular, that it avoids the stare of the other? Then I realized, maybe it is about the social appeal, the way people look at one another and apply stereotypes. It is a game about stigmatization, triggered by appearances.
Another theory, is that the protagonist is some kind of wild scientific experiment on escape, an alien himself, projecting own unlikeness onto the others, marking them as aliens instead. This way, there could be something about quantum physics to the deal, making the protagonist have special quality, as long as others do not see it. Once they see it, it is gone. Therefore, the game could thus be called: "Quantum Collapse" and refer to the phenomenon of quantum superposition.
