I think the dev is just getting the core plot laid out first, and will go back and balance later?
I agree that it feels like a first effort, but its already in B tier for this class of fetish/kink imo. Def keeping an eye on it
it wouldn't be so bad if it was just normal leveling of stats, but not you gotta spend your time getting money to buy a gym pass to work your stats, but that gives you Soul Frags, so you need to spend money to use the Soul frag reducing item as well.
So basically all your free time is one day Job, next Gym, then Job and soul frag removal item, Job, Gym. Repeat until you got enough stats, that's not fun.
The gym should be a way to boost your stats if you want the dungeons to be easier, NOT the only way to raise your stats, and a pitiful ONE at a time to boot.
