Alright so, I'll reiterate that I didn't have any crashes when I didn't use my old saves from the demo version and there were no bugs that I could detect aside from a couple related to the images, I think. However, I also have to reiterate that this is very barebones, and if you want it to be really successful you're going to have to flesh things out more.
I like what you got so far, though, the art is nice and the concept is good and this is an actual NTS game and not an NTR game, so that's good too. I wish you the best of luck with building on this game and I will say again that I don't regret the four dollars I spent on it.
