yes....izuna and shiren are CRAZY HARD!
especially shiren...when you die you lose your ALL YOUR LEVELS AND ITEMS!!! IT'S LIKE BEGINNING A NEW GAME EVERYTIME YOU LOSE!!!ARGGHHHHHH!!!!!!
izuna is much more forgiving...you only lose your items lol
the point of the game is to go in a dungeon,gain a few levels,die,go back in,go a bit deeper this time and gain a few more levels then die.
repeat until you've beaten the dungeon.
I know it doesn't sound so thrilling but it's actually quite a good system for that kind of game...I propably would have beaten it if my sd card didn't get corrupted and lost the save.grr...
to bored to go through the same dungeons atm...
on top of that, "izuna is hot teenage ninja with huge boobs"
an in-game character actually says that sentence lol
I think it's in the 2nd game
