I can't get past Momiji. Nitori deals 2 damage and is basically only good for using items to keep Hina alive. Tube Yogurt and MP items are useless at this point since nothing inflicts status ailments and none of my attacks use mana, so all I can do is pray that I get healing items. The fish fillet increases my max MP, which is again useless; the golden fish just runs away. I haven't gotten any gear upgrades in many runs and I thought the game finally activated some "a lot of money" cheat mode for me, but it's probably just trying to print more decimals than it can fit.
I really wanted to get further to see if I would get to see Wakasagihime in your art style (which, rocks by the way), but I can't take this anymore.
