oooh i like the idea a lot. i'll start with my disclaimer where i haven't played yet because i switched to chromebook BUT i have been looking forward to playing this entire time. ok so i played a lil bit of tokimemo girl's side 3 and the jump from static ds sprites to animated psp was amazing. i'm pretty sure that was live2d at least??? it really gave them life and that was like. years and years ago. maybe 8. live2d is probably even better now. i really like even just the kind of passive sway of the characters. it's all up to you tho! if it's too much maybe a lil gif of him smiling or blushing in live2d would be enough.
also someone mentioned long hair prince and i... also really like this idea... i'm a sucker what can i say
anyways thank u for ur work :) keep it up yo!!
