This is some proper old school point and click horror shenanigans right here. The idea of sifting through a load of individual rooms to slowly but surely uncover the mystery of what's going on in this house of nightmares is a really good one, and I could feel my heart rate going up and up as I moved forward.
The "minigames" added an extra sense of individuality to the game too, a little break from the point and click exploration that added to the overall feel of everything. And the ending was great, too!
Keep up the awesome work, this was really fun and really mind-warping! =)
