This is a nice idea, but at the moment, this isn’t really a collaborative project. It’s a good way for one person to share their work, made in their own style. However, it’s not a very good start for multiple people collaborating together.
For example, your tiles 70x70 pixels, and not 64x64 , which would be a power-of-2 size. While it doesn’t matter for GDevelop, that’s the industry standard. For the tiles to fit together, they would all have to be the same size. If only one size had to be chosen, 64 pixels would be much better than 70.
It’s great that you’re sharing these assets, and you should definitely keep doing this! The idea of having preset graphics packs is also very interesting. However, there’s quite a lot of preparation work that would have to be done before making a graphics pack that’s easy to share, easy for multiple people to create collaboratively, and so on.
Thank you very much for your input and useful suggestions.
It helps draft the idea better giving a contour to what and how assets should be done .
As for collaborative expression… the git allows download and upload of materials (content) — if the settings are correctly made
