The structure to this game is really weird, why is it split into 4 difficulties you have to beat individually, with the world themes being the same? Eh anyways, I did enjoy the challenge mode to this and will probably check out the other modes! It would definitely be nice to see this get a port as being locked to the PSVita is something I wish on no game at all. I imagine playing this with motion controls makes this a 1/5 game but I played with joysticks and it was enjoyable! Definitely not perfect, especially the Advanced levels but a well worth game for any Monkey Ball fan to try, if they can that is.
