not quite there
I love ninja warrior, I've seen almost all episodes so I was expecting this to be a good game. Unfortunately it wasn't that good and I'll tell you why. It seems that instead of putting the player in the shoes of one of the all-star competitors, you put us in the shoes of a fat slow turd (the sumo guy was your inspiration?) :P.
The movement isn't so big of a problem at the beginning of stage 1, but once you get to the two pads that move on the water, you really start to hate this fat guy who you are playing. I tried to take some speed and jump but he jumped like 10 pixels forward :P. Couldn't get past that point.
The game should be difficult as so is the real course in Japan, but it shouldn't be difficult because I'm playing a fat slob. Give me Nagano to control and this game could be enjoyable.
