I'm not sure how to explain this. Giving it my best shot though...
I created an animation programming language called Canvas Language. I use it for gifs, general animations, and games. I would like other people to use it for games. I've created 2 games on itch.io using this tech - see my profile.
I put some game templates on the site. The artwork for each of the games can easily be replaced without any coding and you'd have an new game with your art. The code is also there to change actual game play (Canvas Language code) under the Advanced tab.

I would suggest playing with the Puppy game to get a feel for how it works.
I'm considering having a game jam with the concept being to simply replace images in one of those games and make something new.
Thoughts? Questions? Comments?
Thanks for checking it out.
