I actually put that game down and forgot about it... I remember getting frustrated over not being able to get that healing rod or whatever it was.
Criminal Girls feels like a standard dungeon crawl from what I can tell (with it's own unique story obviously) with a ton of touch pad (front and rear) mini games to actually level up and learn skills which are different than your base level for some reasonbut your base level determines how much damage any of your attacks will do.
I am currently on the frost block which is 3 bosses in and only really needed to get used to the enemies attack damage, how much hp they have, and how much damage my attacks will do. After the first 5 mins on a floor or "block" of floors I just camp the save portal to level and money grind with no issues.
Feels like the generic rpg formula with yet another unique NIS leveling system and a different story. Nothing terribly groundbreaking.
