Played this as part of a Halloween stream, and found it to be an incredibly average indie horror game. There are some nice touches, such as how the titular Mr. Hopp changes in appearance the further you progress, and the sound design is great, especially in a game like this where you need sound to be able to predict whether it is safe to move or not. The game is reminiscent of Clock Tower in a good way, mostly.

That being said, the game is absolutely dragged down by the gameplay, which consists of extremely janky platforming over objects on the floor. Very awkward to play, though this is the first one so I can't complain too much. Maybe the sequel is an improvement.
