Remix this project that contains some starter code. Then you can make your own customized platformer game: add a score, add obstacles, add new levels... Use the left and right arrows to move blue. Use the up arrow to jump (press and hold to jump higher). Travel to the flag on each level.
I used the following resources when developing this: https://inventwithscratch.com/book/chapter9.html https://en.scratch-wiki.info/wiki/How_to_Make_a_Basic_Platformer See my example at: https://scratch.mit.edu/projects/374303665
