First thing first, THANK YOU for this game. It's amazing, I came for the adult game, I stayed for the story and everything around. It's well written, funny, really immersive and absolutly brillant, it actually interested me in the VN genre so much that I only play that anymore for the moment.
If I had to be picky and to find a single fault, it would be about the H scenes. Sometimes the characters seem to lose their own identity and to become random pornstars talking crude, it's a little odd, especially when their usual timid behaviour is the thing that make them likable in the first place for exemple.
However, I have only played the 2 first chapters for the moment, and things may change after. And as I said your game is so good for everything else that this little fault is a minuscule prize to pay for ejoying such a gem.
I hope there will be tons of other chapters, for the 40 years to come. By the way, is there a end planned ? Do you intend to keep developping this game for many chapters again or will we have to sadly say goodbye to it anytime soon ?
