Platformers are hard OK? Use the arrow keys to jump, to run, and... that's about it actually. Time to make: 1 hour. time to play: 5 seconds.
Click here for me trying to do a platformer WITHOUT the help of griffpatch. https://scratch.mit.edu/projects/99389162/ HUGE credit to griffpatch for his tutorial on making platformers. Plus, he's just generally awesome.
