I think if you want to use an established IP or horror 'entity' in a game, you have to make the hard decision of trying to establish it anew or create a fan game. I feel a fan game around ben drowned would be ideal here, as the experience is fairly short and you could have reused the entity in a "weeping angel" style towards the end (instead of an enderman-esque entity). I feel with a little more lore or swapping models, it would be a better experience. Thanks for the game! Linked at the time I played for convenience.
