Thanks for letting me know, and I'm glad you're having fun! If you email me at balloondra@proton.me or DM me on bluesky or FurAffinity (@balloondra) I can send you specifics!
Please be aware that it may take some time before I can properly quote you a price; I may be expanding how much content there is per character in the next update and I don't yet know how much extra work that will involve. But, expect it to cost at least $400, owing to how much art and character writing I would need to produce.
Alternatively, if you wait long enough (another year maybe???), I'd like to eventually add a "custom character creator" feature. You would need to supply all of your own assets, but it would be totally free.
