To make a basic platformer, go to https://en.scratch-wiki.info/wiki/How_to_Make_a_Basic_Platformer. I also went to the exact same site, and that's how I made this platformer. My first platformer works! Please check that site if you don't already know how to create a platformer., That site really helped me create this, and probably help me in the future with my other platformers! Please tell me what to make of plaformers in the comments below. See the games that my friends (BlueRaven35 and aryansinghal123) made!
