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.
