Hi,
Thanks for answering.
Apart from designing and drawing the UI, the idea is to start with at least:
-Backgrounds: between 2 and 4.
-Characters: between 2 and 4.
-Objects: approximately 16, preferably related to the backgrounds.
In order to be able to add content more easily in the future, we could adopt a style similar to Peppa Pig or Ben and Holly.
I hope you are available and can join me in this project.
