Heliosphere

The path is long, and the rhythm in the second half is so weird that playing it on-beat causes loss. Most of it is a winning run section, but it suddenly spikes in the second half twist, and it seems like it'll be very tiring for locals. The reactions in the YouTube comments saying it's not a 14 are really over the top; the difficulty seems similar to or slightly harder than Hercules. Depending on individual differences, it'll probably be around low-mid to mid. It has some long-job elements, so you can get a taste of the basics of long-jobbing.

I tried it again, and I think it's a mid-level. It's too stamina-heavy to be called low-mid.
