I got a kick out of this game. I enjoyed playing through it - it set up some scary vibes pretty effectively, built tension throughout, and seemed to execute pretty well. The intro was a great first impression. There's an obvious connection to the theme .
Only complaint I had was a little weirdness with the invert-y option - had to fuss with it a bit to convince it to give me mouse controls I was happy with. On the other hand ... I was really happy that the option existed, though, so thank you for including it!
