I got Doraemon Meikyu (Cratermaze), and Peach Boy Katsugeki today. My original copy of Cratermaze has yet to be replaced, so I bought this one for fun while I wait for a reasonably-priced copy. It's just as fun as the US version and I like to see the different characters.
Now, as far I can tell from playing for about an hour, Peach Boy Katsugeki is pretty rad. In terms of gameplay, it's somewhat similar to Zelda II on the NES. However, I didn't realize just how much Japanese text there would be, and it's hindering my progress a little. Eventually, I'll be able to figure most things out from trial and error, like how pausing the game and choosing the second option grants me various amounts of additional HP (but why?). But I can't figure out at all what people are telling me in the town, so I sadly must pass them by and only use the "stores".
I do love that you can upgrade your weapon and the graphics are really nice -- super colorful like always, and the "demons" look hilarious. I also like that you can land on just about anyone's head and ride around on them, like in Doki Doki Panic/SMB 2. The jumping could be a little better, but you get used to it fairly quickly.
If any of you have this game and could translate or fill me in a little better, I'd be really grateful. I'm still gonna keep at it and figure out as much as I can. It's a really cool game and doesn't cost much at all.
