I played the demo for a bit. Unfortunately the story didn't really hook me, so I can't really talk about it (I stopped playing when they first go to the cafe).
The English translation is a bit awkward, there are a lot of grammatical mistakes and wrong use of words, and since this is a visual novel the experience suffers because of it 😕 You could probably recruit someone to read through the translation and propose fixes.
As for the visuals, the game is very cute with a nice color color scheme, it's very pleasing.
I've seen the credits, you've assembled quite a team to make this game! It must be fun building it together 🙂 Good luck!
