I have one main thing to point out.
While there is really shaping to be very interesting, there is one thing that I think heavily detracts from the reception (past starting with sex with the OC).
It's the banner on top of your page on the itch.io.
It makes Izuku look not like just an edgelord but as someone actively evil that's playing those girls around.
However, by the time of the current moment in the story, Uraraka (with Tsuyu's help) has kicked most of such behaviour out of his head, and while he is far from his canon self still, the core of his personality (wanting to help others) is still there.
You should PROBABLY get a new banner because this feels like a great idea to push a lot of people aside - you have the rare benefit of having Izuku as the protagonist instead of a random OC, but you're seriously wasting it with that damn banner. I know at least one person who saw it and decided not to download, and since that's the only person I know that even knows about this game, it's not exactly looking good.
