I really like the art-style and premise, yet had trouble playing it. It's more of a personal skill issue, but I got lost multiple times, not knowing what to do exactly. The pinning mechanic got a little bugged as well, making me unable to place anything, had to click and drag around all over the place to make it detect my input.
But all in all it's good, terrifying and atmospheric. Totally recommended!
Also where is the sigma option?
