I think you should already know how to play a platform, btw Happy Earth Day! I made some differences, I added a plane, bird and some different colored lines on the earth parallax. - 4/23/26
Credits to @TerribleGames123 for the platform shape(Not the trees and bushes), The player's, spike's, and lava's code. Other than that everything else was me. Here is his project. https://scratch.mit.edu/projects/844126634 Took 4-6 hours for the project (mostly because of my art) but, not to shabby I guess.
