In All Coils%, skipping checkpoints (meaning, not touching them) is a viable strategy. Why? Well, when you get a Coil from a bonus stage, the game sends you back to the last checkpoint you touched, not necessarily the checkpoint that the bonus stage was located in. This means that if you skip some checkpoints before you get the Coil, you'll get sent back further after obtaining the Coil and won't have to backtrack as much, which saves a lot of time.

Of course, the drawback to doing this is that if you mess up and die, you'll have to redo a lot more, and resetting intentionally to gain more HP/Elevator Coil boost will not be an option, which can potentially cut off a few skips. You also don't want to skip checkpoints if you have to get two Coils on the current path, because then you have to redo more to get to the second Coil, which wastes time.

Overall, skipping checkpoints can be a very useful tool in All Coils%, but just use it carefully!
