Alright, I'm on the eighth world - technically the last world if you don't count the two hidden worlds - and I have to say, it didn't take long to get here. I finally figured out how to hold the controller in a 'neutral' position (which is something like a 30-45 degree angle) and since then I have become pretty damn accurate with the wiimote. I at first didn't believe this control scheme worked very well, but now I'm willing to retract that.
A couple of notes:
The later you get in the game, the trippier it gets. Holy shit, space is
ing beautiful!
In Monkey Ball 2, I noticed there were a lot more large boards to play on with tons of obstacles, whereas Banana Blitz opts for thinner pathways and goofily long courses. I'm not sure which is more difficult, though; I found myself fighting the timer in SMB2, but now it's more a matter of navigating the crazy rollercoaster-like pathways.
The bosses just aren't difficult. It takes a number of tries, but many of the times that I was knocked off the battleground I felt less like it was my fault and more like it was a fluke. Granted, the most difficult time I've had so far is chasing the little rat thing that commands the large creature composed of balls, but that was more a problem with the camera angle (low and facing the boss) and the controls, which don't cater to quick-turning chases, and less a problem with the boss itself.
EDIT: The final boss is mega easy!
The minigames aren't worth it. Period.
The single-player game is very satisfying. The last time I was pumped because I beat a level was when I finally finished that insane firefight at the end of Black. SMB is a very gratifying experience, if short-lived (played the game on-and-off since launch).
Hope I get around $30 for this in resale value. Anybody have any idea how much this sells back for at EB, GS, or GC?
