It was so unexpected yet totally awesome as well! It was just randomly found by us and we just started to do our thing. Of course the Lil Broski wanted to play after that. Overall I really dug it. They should put it in future games. It was fun and simple.
Well... From what I remember about it I liked it. But it WAS just a little side gimmick and it really had nothing to do with the story... (Much like the minigames on Destiny Island) But it was a fun little distraction before actually venturing on with the story
