For me, the controls were weird, but absolutely not impossible to play. It was okay to play.
Interesting proposition, polished, puzzles on a good level of difficulty for me, but probably too simple for veterans. It was scary, but again at the perfect level for me. In other words, it feels like a casual game. Which is by no means bad, I think it's worth recognizing your target. I'm in the target group - experts in puzzles or horror fans, not necessarily, this is why I'm saying that it can be labeled more as a casual game.
Teleportation and these moments of changing surroundings - great effect! Works beautifully. I appreciate that you didn't use any of this stuff like sudden loud noise or something jumping at you. I hate these tricks. In the tunnels I was terribly lost, but it's good :D
Thank you for that game!
