I haven't played anything quite like this before. It ended up being surprisingly immersive being forced to pay as close attention to the game environment as possible. This turns out to be a mostly enjoyable horror-ish game of "spot the difference," but I will say that some of the differences were so subtle that they were almost frustrating when missed. Cool way to burn an hour and I enjoyed seeing some of the wackier anomalies.

Great little experience about paranoia and liminal spaces in public transport, two of the things I deal with almost daily. The worst feeling, walking past a corridor you "believe" is "normal"

Nothing scarier than nothing being wrong.
