Monster has to chase humans to put them in jail, humans have to hide and run from the monster. It's a simple game anyone can get the basics of whether they choose monster or human, and there's a bit of variety in each monster's movement and way of catching their jailbirds. Playing as the human and just barely slipping by the monster's clutches by jumping right through them or hitting them with a well timed lantern can be pretty fun, too. It's a good choice for a Game Trial, especially for Halloween as it oozes the "cutesy spooky skelly" side of it. It's a little too simple for $20, but $10, that's alright.

Also, you can play as Leon Belmont in his endless journey to put every child and/or Alucard in jail. I have never played Lament of Innocence, but I'm going to assume that's canon.
