I was able to end hard mode with 45 potions.
That's one of the top run I've seen!
The dungeons are separated by sections, each sections have 10 floors. In Magirune 1, section 3 had a higher difficulty. It will be the same in the full game. Hopefully it'll be ok.
The reload exists because I wanted to give a "chance" when people come back after they stop playing. The problem happen when people abuse and just reload. Reading you comment got me thinking. Maybe I could give full heath if there's a difference of 10 minutes between the last save and the reload.
