The clone feature was a one time use, which I didnt know, but I restarted the entire game and was able to finish. The silhouette style is really cool, and reminds me of my game! :)
Just a tip: because your doing movement with velocity, put a frictionless physics material on your character, up the linear drag on the rigidbody, and then adjust the jump force and gravity scale to compensate. This will make it so your player doesn't stick to walls anymore! :)
