I liked the art. The textures are nice and evokative of something horrific. The music is too, but could use some variation.
It’s clear this is a start of something. So, I won’t tell you things I think you already know. I guess I would like to see some sort of patrolling behavior to the killer, so it doesnt’ just immediately travel to the player. Only when it detects the player should it start tracking them. And I think an end point to the game would be good. Like, make it out of the maze and you get a “you won” screen or something.
