Hi. I was one of the streamers who participated in the Feedback Quest. Before anything, I'd like to give a warning on what I am about to say. I am going to be very critical and frankly quite harsh in my critique. Its even more so in the VOD of my stream. I sincerely apologise in advance if I offend.
I had issues with the game from the start knowing that it was made using AI art. As an artist and seeing the results of AI towards myself and more so my peers, its very common that AI Art will put off a lot of people. I believe in your sincere effort of making the game but I would recommend that you either stick to limiting the character models and just using one rather than multiples of the same character as the switches stand out a lot and a reasonably sharper eye will notice it. It shows in the background, it shows in the saturation. The UI also feels lacking.
A Visual Novel is often built upon two things, the art and the story. The art for this is frankly a weaker element of the game so now it hinges practically entirely on the story which sadly doesn't work. The setting of 1992 would not have words like "Normie" there. Since the art was such a point of contention, any small mistakes become magnified even more so. I've also noticed a LOT of scientific theory in the route I played which frankly, I do understand a lot of it but even if it is essential to the plot, feels forced, too convoluted, and unnecessary. It would put off most people before they even get the pay off of said information being used. There was also a lack of believeability in the world as it was. Suddenly being transported into 1992, having a cat eared girl with little to no explanation, there were too many jarring things that made me lose connection with the world and it lacked believeability. I found myself pulling away often trying to process what I just read, to reconcile it with what was introduced at the earlier segments of the game and such. Another thing of note, the main character at least to me, thus far has been very unlikeable. Him calling girls Nerds after establishing that he himself is a Lonely person who had no friends now suddenly having girls vying for his participation and him dismissing them. His character lacks believeability.
HOWEVER there was one part of the game that I played at some point that I truly enjoyed. It was when they played the RPG tabletop game. The art for their game characters and the lack of switching designs, the fantastical writing and build up of the world and surrounding, the very descriptive writing used and interesting plot albeit the fight in it was a bit hard to fully enjoy but again, it was good. I feel a genuine knack for Fantasy Writing. You made a believable world of a TableTop RPG and it felt genuinely good, I FELT connected to it and invested in the story. I feel that you have good strength here that would benefit in the future.
I praise the effort and hope you will keep making more. I enjoyed the bits that I enjoyed very much. Again I must apologise if you did see the VOD or read this and are taken aback. I hope you will continue to make the games you love.
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. ;)
