Happy Snake makes a lot of cute games, though this time they tried to make something with a little bit of horror in it. QT is kinda like a reverse horror game, in that it starts spooky and then gets full of good feelings instead. It's also a big reference to P.T.
The game is currently on Kickstarter, but there is also a free Demo that can be tried here:
