It's fine, it does exactly what it tries to do without any interesting twist. Some puzzle rooms are good, but some of them are total nonsense and badly designed. The art style is just too plain to be any interesting, although there are few rooms that look good. Two of the themes are really good and interesting (Egyptian and Victorian era) while the other two are really boring (Megacorp and Space).

Like I said, it's fine. I got bored halfway through the game, but I played the two least interesting themes last so that might be the reason. Also, I played alone, maybe it is better with more people but I doubt that there will be much difference. I’m giving it 6/10, it was a really mixed experience.
