Thank you very much for the stream! No worries about being critical, but let me be open too: Ai art has its limits. The whole process of making this game is about exploring exactly these limitations, so take it as a service for artists to have something to roast. ;) On the other hand: if you read the reviews of non-artists for the game, they typically mention that the graphics are nice. So while artists easily notice the glitches and problems, usual players might not. (That is something to worry about as an artist if you see AI as a competitor.)
Regarding the science content: how much of that you get depends on your route, of course. As the game is called "science girls", however, the trigger warning is there... ;) I don't only want to tell a story, I also want to make the players get a bit interested in science topics and to learn something. If I achieve this with some of the players, it's good, but of course I'll take your comments and try to improve on that.
Your critics of the story logic or the main characters' attitudes is understandable. However, all of these points are questions that will be answered later on in the story, e.g., the main character changes his negative attitude over time. (It's a story about self-improvement if you want.) You will also know how he ended up travelling back in time etc. at the end of the game. Also you will learn in Azuki's arc about why she has the cat ears and who or what she really is. – As an author it's always tricky to strike the balance between explaining everything upfront and keeping some suspense and mysteries to resolve them later. If one goes for the latter option you might end up having players like you who conclude that nothing is explained and everything is random. If one goes for the former option than the story might feel predictable and boring.
In any case, thanks again for streaming and for your comments! :)
P.S.: I also like a lot how the RPG came out. ;)
