I liked the sling traversal and it felt good, but the electrical wiring part was tuned to require too much precision considering where the checkpoint was. It became extremely tedious to fail the long shot to the end, where you have to take 20-40 seconds to get set back up to attempt your shot again. From a difficulty curve standpoint, the first level requires too much subtle mastery of the controls and that kind of punishing scenario should come after a few levels of practicing other techniques and feeling out the controls.
This concept is great and has legs as a larger scale project.
