I love these! They are still pretty tough, but it’s comfortably tough for my skill level.
I felt like a fox diving into snow on the first 2 jumps in vol 1, I also got a weird kick out of the tip of my thumb automatically placing itself over the run button when I got onto that donut.
Also want to mention another favorite of mine, TCM-ん. They don’t make precision levels, but they are difficult and technical. The challenges they make are focused on enemy behaviors, 3XD-2MY-8PG and NJS-WSD-89G are my favorites so far on their second account.
