I was promised wholesome and cute and thats exactly what i got, you did a amazing job, I even played the short 5 minutes part (i hope it is a teaser for a bigger project :3).
I really like the tone of the story, you manage to immerse the reader by making the main protagonist relatable and kind of shy and quirky, his chemistry with Dawn is adorable and it makes playing the game a really lighthearted and fun experience.
I also like that you didnt put bad endings or mean decisions in the game, i'm not against suffering the consequences for your actions in a visual novel but it is kinda sad when i have to choose the bad decisions to finish a game100% XD.
Again, nice job! Hope you have more prepared for us : D
