I am not going to lie - I don't quite get this one. Or for that matter, how it supposedly relates to Junji Ito's work (aside from the snail imagery). I realize it is a two-minute game, and thus there is little room to be too elaborate with stories, but this comes across a bit as "walk in a straight line to the spooky thing".
This is not bad as much as it is a bit bewildering, however. The game looks great, and the imagery of the supernatural creatures is wonderfully unique and unsettling. I'd just have liked to have some sense of what was actually going on, as I don't feel there's quite enough here to justify a surreal experience.
But still, I did quite enjoy the experience.
