Saying your inspirations being Violet Evergarden and Chuunibyou Demo Koi Ga Shitai put me in limbo knowing that combining these two will bring an anime that will definitely bawl my eyes out when emotional scenes kick in.
I like how each track can be used to portray each scene in an episode like the "Enemy" track being used when the protagonist is on a delusion of sorts, "Dumb Antics" being used for the Slice of Life moments and the sixth and seventh song being used when I'm gonna cry.
I could totally see this as a Slice of Life anime with a lot of comedic and sad elements sprinkled in it and even a quirky cast of characters, kinda like Oregairu or Love is War. Amazing Work out there
If you really want to make it as a game, simply put it as a visual novel lmao. Also missed opportunity to make the title in some songs have old English words like "Thou" or "Thy" to characterize the protagonist's 8th grade brainrot.
