I'm on the fence but I won't ignore or drop this just yet. I submitted my review and as such I will keep this short. IF future content is in fact as described in that Patreon post, with the different female characters getting different gimmicks in their fetishes, and these fetishes being good or passable, I will not lower my opinion all that much and even may raise it.
Ochako alone having a prostitution route does not make or break this for me, but if similar treatment is done down the line to other characters I will re-evaluate my review and opinion. I firmly believe that the backlash would be lessened even WITH this update if the dev had worked on other, more MC-focused content first, instead of making the first real look at the character routes being a prostitution one.
That said, just read the review if you want my full opinion. I'll be keeping a cautious eye on this.
