Jump over the spikes using the up arrow.It gets faster every time a spike is passed. Try this game out next: https://scratch.mit.edu/projects/1049117159/
I did this with no help, although I did use art from one of my other "failed" project. (I made the "failed" project with no help too.) If anyone wants to see if they can fix the failed project with me then that would be great, thanks! Just comment if you do! :)
