Yeah, next non-hotfix update I'm going to be addressing the crit situation as well as beefing up player characters so it's harder to die in one or two hits stray hits, and I'll look into the targeting thing at the same time. I'll have to look through my plugins again and see what's up, I think I put in one that shows your full range of attack instead of just the things you can target, it's possible that messed things up. That or I'm missing a setting somewhere, that's also possible, the layout in SRPG Studio is...janky at times.
I'm gonna keep an eye on the growth rate situation as things go forward, probably study other games' growth rates a bit more closely so I have an idea of what works and what doesn't. I just went with what felt right at the time (and how they compared to other PC growth rates and playtest tweaking), so they're probably not the best ATM.
