Nightmare's diff needs at least -2 HP drain because of last slider. It drains ~1/2 HP bar and after those last jumps it most likely makes this map impossible to pass.
also worth mentioning:
[Extra]
01:15:022 (1,2,3,4,5,6,7,8,9,10) - this stream is a huge difficulty increase, hexagonal hugely spaced circles are quite hard, and after it map gets sane once again for some time, in fact, it's about difficult as last jumps for me
I find it really disappointing that all diffs here are all about cursor control, if this mapset had a diff made for people who like smashing keyboards, but are so-so at mouse control, it'd be really great.
