Please forgive me as I often forget to reply. I will answer any and all of your questions and requests.👍
I'm planning to add the system to choose the animation of each character in the future. It's especially difficult to express the movements of small characters in a gallery, because they are not in a single picture.
When the game is finished, I plan to sell this on steam for 8$. However, I may release this for free if I can get support from patreon or other.
