Thanks for the bug report Aphrodite, it should be fixed now.
Thanks for the mention on the music(s)
Indeed the "management" part is calm and soothing on purpose, since it's more a reflexion and "no stress" part of the game (although you don't want to be out of money with sirkles that can't fight).
I'm a bit sad that fights feel random, as they not really are.
The stats do play a role in each attack. It's a bit obfuscated indeed though.
The formulas behind the game :
Fast attack and Light defense rely on Speed, Strong attack and Heavy defense rely on Force.
Attacks cause damages, Defense cause a reduction on those damages.
Dodge makes a reduction based on speed + dodge stat
Special deals damages based on speed + force + special stat
Thanks again for the feedback
