Finally got it working (I dunno why, I went back and checked and all the values were changed correctly...strange). Anyway this game is pretty damn boss, especially if you're a Kamen Rider fan.
It's pretty much like the Scott Pilgrim game for PSN/XBLA, but unfortunately not as polished or as good to be quite honest. The same genre setup is there, you level up in a beat-em-up and gain new abilities at certain levels.
Unfortunately the levels are really bland, there is a few platforming segments that are terrible, and most of the characters play very sameish.
For the most part, every character has the same moves, which is strange cause so much effort was put into the animation. This is, however ignoring W and OOO's alternate forms, which are fully playable in this game and very different from the usual. The problem? Not all characters are like this. Kuuga for example only has moves that represent his other forms. None of them are playable. With the exception of W and OOO, all characters are like this which is disappointing. Decade also has alt forms (sort of) in that he copies all of the other rider's moves, which you progressively get through leveling him up and/or buying them from the store in-game.
The game is sometimes offensively easy while at other times there is cheap hits like when magma rocks are essentially raining on the field, it's very difficult to dodge those when you're trying to battle. Being easy is a good thing however since the game has pretty much no English text in it.
But this is a very authentic Kamen Rider game. While I'm not finished (on the final level) and I haven't unlocked all the riders yet, all of them play exactly what you would expect...even with the similar moves. There is an incompleteness with the other characters with multiple forms, you still can't play as anyone's ultimate form, and the only secondary rider in the game is the one from OOO's. In these regards it's disappointing, but what's there is better than any Kamen Rider game before it.
