Binged this yesterday, the quality of this game and interest in the Ochaco game definitely earned my patreon support. I figured I'd leave feedback, as I'm excited for more. Sorry for the wall of text, I like to be thorough.
Gameplay: Actually pretty fun. I saw a discussion on armor and money and I'll agree that it can feel like there's a ton of pressure early on in how expensive upgrades are, and not knowing when/if you should buy your upgrades. Still I managed to get through with only 2 people having tier 2 armor. Combat at current state feels balanced and fair, and I got through without ever buying info and only game-overing once (It was Davy fight. One character got nuked hard and I just let myself die so I could restart and buy the water accessories). Would like to see more options in combat over time, but right now it's a really strong foundation that I enjoyed for the most part.
Plot: Actual plot is pretty tongue and cheek with enough serious moments to keep it from feeling like a complete parody/comedy. I usually didn't feel like I was being given too much exposition at once, and I am 90% confident I understand general plot and character motivations right now. I like the current direction of the story, though I hope it doesn't go to the realm of absolute monstrosity some parts of late MGQ3 hit. The justification for the harem feels a bit like a handwave, but takes it self seriously enough to be believable.
Girls: So far I like the variety of girls as far as looks go. On the personality side, I like the general attitude that everyone so far is enthusiastic in consent and the writing hasn't stooped as low as "Oh, you saved me from a mild inconvenience, I'll give you my whole life". Even the ones appealing to an audience I'm not a part of (example, I'm not a fan of the werewolf girl, being mostly just ok with full furry girls and not a fan of pet play) I still liked to a decent degree. All the girls feel unique in design and personality. On specific girls, I like Ray for her slow build up and cuteness. Nice change of pace from the usual boner-jumping girls. Bessie is adorable and I think the writing for her, her predicament, and her growing conflict are handled well. I think it'd be great if you could bring along a rotating 4th character to build relationship/have the waifu around, but I understand if that's just a lot of extra variables to account for in writing that wouldn't be worth the massive effort. I guess what I'm trying to get to here is though the girls are drawn sexy and written horny, they are treated with respect as characters rather than just porn objects, and that's fantastic.
Conclusion: Game's pretty fun even without the porn aspects, and even if it was just an ecchi/tease game I'd still probably play and have fun with it. Girls are sexy and well written, and I'll be looking forward to every release.
