Hi failbrain,
I would like to create something similar to
https://www.amazon.ca/Reusable-Sticker-Innovative-Activity-Toddlers/dp/B09FL9Z6YP
I have uploaded a prototype at
https://donnadie.itch.io/kids-story-maker
As a 2d artist, you would be in charge of creating all the art from scratch (backgrounds, characters, objects, UI/UX design).
There will be a free version and a premium version that will offer extra content.
It is a revenue shared project.
You can contact me here or my discord: donnadie#4307.
I sent you a friend request.
Let me know if you are interested.
