Played the game because of the ominious title and didn't disappoint! Sory my video doesn't get all endings, though I tried playing after I made it but couldn't figure out where to get the wires.
Overall it was a really fun game with a really cool concept. The map which falls down and has a time limit till you reach the end is a really nice touch and done really well. It gives the player enough time to get things done andpiece together the story as well as take in the enviroment.
The way the game looked really suited the overall feel and game itself. It was gritty, dark and had an air of mystery to everything. It made the shadows down below seem pretty spooky and also made the game seem very unique.
The idea of having floating pages around is a great touch though I might suggest making those notes be different (I went to one of the notes that was floating and it seemed similar or the same as one in the large generator room in the attic area.)
But yeah, overall it was a great game with tonnes of incentive for replayability. You've done a great job on it and good luck for future projects!
