So I'd not played the dev's other version of this that it's a reskin of as I'm not into that anime style engine, nor really parodies ... but this I was definitely up for as I really enjoy corruption and whoring out girls and things... a few things I noted as I went through...
The tutorial had me worried for a second and might need rephrasing, as the person states that her and another are on the harem route and the 3rd is on the whore path ... which made me think for a second that you couldn't pick a route for each girl but that different girls catered to different things ... as that's not the case and when you start the game none of them are on any routes I think that line should be removed.
The frog girl bit is totally out of place. I get it's a reskin of another game and I presume that is trying to tie it to that Hero Acadamia character ... but calling her froggy (even if you change her name that persists when buying swimsuits and stuff) and her silly starting costume was all really offputting, even if you try to explain it away as a mascot thing ... personally I'd rather all that was cut out.
I did a second playthrough to see what the harem path was like, and as she has more content there it was even worse, her saying 'ribbit' and things during sex and talking about how she was a horny frog and whatnot - I was super not into that.
Also while her swimsuit stuff plays out fine in the harem path ... on the whore one you still have to give her the most basic swimsuit (it won't accept slutty ones) but then what she's wearing is actually a different one, I guess from how the scenes have been cut up - and it kinda doesn't make sense.
Likewise, Rachel was sometimes referred to as Raven (I'm guessing the name of the character in the other game carrying over) ... but this just felt like a typo and wasn't as bad as the frog stuff.
My other complaint for her was that if you gave her a reward she'd still stop working unless you gave the the "motivation for work" reward ... whereas I feel like reward1 and reward2 should also count for that.
I wasn't super into the navigation of the school at the start and would have liked the traditional list of rooms when in each location and click which one you want - but once you've met each girl once that problem is gone with the direct to room buttons ... however that does introduce it's own slight problem as I realised I never actually clicked on the school (rather than skip to classroom, library, etc) and you've gotta do that to see some events, like Rachel not wearing panties to school.
I wasn't into the stamina system when you've already got a time advancing mechanic ... but it's less annoying once swimming takes less stamina.
Likewise I found money grinding early on a bit of a pain, but that's also not a bother once the teacher stops requiring money and you've got Rachel working (though I don't know why you couldn't have Rachel still work in the bar on the harem route - that's a long way away from prostitution).
My other slight qualm was that the MC is so generic, I wasn't sure if it was him sitting next to Rachel in class watching her masturbate, or another random dude ... I'd like it if he would stand out a bit more so can tell easily when it's actually him, haha.
But that said, the scenes were really hot, I enjoyed them ... even on the harem path all that stuff about the teacher getting fired and moving in and having your baby and whatnot I was well up for ... so I might have to keep a savefile for each route and play both ... I found the teacher and Rachel both really hot (pool girl was a bit boring, but maybe it was all the frog stuff turning me off) ... as I said I'm really into the whoring thing, there was only a little bit with the teacher so far but I'm interested to see how all that plays out.
So yeah, I get I listed some complaints but I was really into it, I hope the whore path goes real dark and dirty but it sounds like there's plenty of gangbangs and prostitution coming ... I'd be up for some breeding material even on the whore path for some girl ... and I hope to see more girls and more content ... good luck.
