Yeah, keep going. If you want to revise the earlier parts, that's cool but not absolutely necessary right now.
By the way, the deciding factor for me to give your game a shot was the "C*ddling, k*ssing, h*nd-h*lding" tag. These little intimate interactions during the events of the story already go a long way to make the relationships believable and not just confined to individual lewd scenes. I also like the interaction between Natasha, Gianna, and the MC after his trip with Gianna. The conversation felt right, and it's good that he puts Natasha first and keeps her in the loop.
