I went into this expecting a super cute platformer game, and my god, never judge any more books by the cover. About half way into the game, it started going to hell, and I mean litterally, there were black arms with red clawed hands shooting up out of the water!!
Backgrounds get gnarled and twisted, death screens give you occaisonal messages such as "Ready! To die", "Stop", "Give up", and "Mother", it truley turns into something you'd see in an internet creepypasta.
It's very short, I was able to complete it in under an hour, but very entertaining. I'm not sure if I would call it worth $4.99, so maybe wait for a sale to get this odd little gem of a game.
Moral of this story, book covers can troll you.
