Switronic

this is basically the S15 chart, but completely filled with twists.

The part where you have to step with twisted legs after the late big stairs is very confusing. The section after the slow part is the make-or-break point.

Reading is very difficult for locals. A chart you should play a lot if you want to move up to higher levels.

Beginning - Oh, this is doable / Ending - Oh, uh-oh

It might be a bit tough for locals. High nutritional value and fun.
