REALLY hard, if you touch an enemy, the screen goes blue to show you that you died. Also, it is no use camping on the edge, I made it so after 5 seconds o n the edge, you teleport back to (0,0). I don't care if you aren't camping there, that's just how it works.
Thanks to @pikachu0601 for the music from his featured project, True Chaos (you should check it out, it is peak. The link: https://scratch.mit.edu/projects/1314488107 ). I made the music reversed BTW.
