This was so good! Loved the different creative *badum tish* creatures in the game and how they were dealt with. It was also so spooky and loved playing the game and going through the story!
I did feel that though the story seemed to drop off at the end and there didn't really seem a point to it as nothing happened except a reference to the name of the game which... Didn't really fit. Maybe something spooky happening to the nephew or like a battle would have made the story more tied in and fit well!
Also the creeper-darkness part was a bit annoying as once the monster spots you, there's no point in running away as you can't. Making that boss fight room a little larger and the ability to run away and hide would have made it way more scary as it would have given each attempt more of a reason to run and keep trying and hence made it scarier!
That being said, it was still a really enjoyable game, scary and well made! Congrats on making it and good luck with future projects!
