In Monsters (probably) Stole My Princess you play a vampire named Duke. Duke returns home to find that his princess has been stolen by monsters, probably. So you then do what any person would do, you go to confront the monsters who probably stole your princess.
Once you do this the game is on. After a funny little chatter between Duke and the Monster, the monster takes off and you have to catch him. At this point it's a vertical platforming race to the top. Duke has to hit the monster three times before he passes the finish line at the top.
To hit the monster you have to jump onto them. Two things you have to look out for when doing this, first you have to hit the monster in the side. This became very aggravating to me. If you hit the monster from the top you pass right through him. The second thing you have to be careful of is having a landing spot after hitting the monster. If you don't you will fall to far and will not be able to catch back up with the monster in time.
Overall for a mini game this game is funny and fun. With only five levels it's kind of short but I think worthy of picking up.
