I'll give you some genuine feedback instead of small YouTube channels telling you how amazing it is because it's spoopy. 

I really, really enjoyed the idea behind the game. An old mansion that drove its owner insane? That is prime for some atmosphere and slow puzzle solving goodness. 

All I got was walking around the house for 5 minutes at the pace of a snail and a boring sewer section with the png of fallouts lockpick mechanic. 

The interaction system was weird, I don't know why you can pickup shotguns and spin them around? There's three of them in this 15 minute game. I'm not even sure why you can interact with things? The only thing you need to pick up is the VHS next to the tape player you need it for?

Speaking of the sewer, the code puzzle was bizarre? Why would VHS tapes go into a vending machine after they're played, and have numbers on them? Like, seriously think about that for a second. Also, we're in a SEWER? Why is there a Coka-Cola vending machine down here? And if you are going to put numbers on things, try not to make them about 4 inches from the thing they're supposed to be on. 

The two side pillars in the sewer have no back texture by the way, so when the very out of place ending "scene" (to be very generous) plays, you can see through the walls. 

Honestly, while the game is playable, and works, the fact you charged for this? Shocking honestly.
