Thank you so much for the detailed review!
While I am still worried daily about the characters, seems like for the most part, they are very well received and detailed.
Yup the Gallery will be added inside the game pause menu, it was meant to be added but I forgot, ups 😐.
For OST itself, it's a bunch of non copyright songs. Rather not have it as downloadable, but maybe one day I can compile a list at least. Will see, no promises.
