What saves are you looking for? If there's one in particular, the most tricky one I find is the Landlord + Loan Shark moment of truth where you can easily mess up. I would just use the saves already provided personally.
After playing, here’s my review:
I played the developer's previous game, 'Me, My Girlfriend, and Sparklers,' so I already had an idea of what to expect: a 3D NTR game with multiple routes.
I can see how much the author has improved, and I eagerly await their next project
I think he's not done with this game just yet. It was a pretty good success and over the next year if the DLC is good, he'll probably get even greater success. I think he deserves it. "My GF and Sparklers" had some really great writing, and it hard carried the stiff animations. Aoi and Nagisa are insanely cute, and their characterization is some of the best. You really feel bad for them, and protecting them is great motivation. Which also becomes kinky as hell when they are taken.
Unfortunately he's doing a "Shitty brat" DLC next which is boring to me, but if he adds some good Oyakodon to the main routes, particularly the insanely rushed Sakata and Landlord route then that will elevate it to one of the best.
