This is my second platformer. I coded it in five minutes! That should be a record or something! So you all should know that this platfromer is easy in my opinion. Again, https://en.scratch-wiki.info/wiki/How_to_Make_a_Basic_Platformer helped me a lot. To go to this site, just copy and paste the link! And I know that it is super easy :) :) :)!!!
