it seems pretty quantized to me, just some land on yellow ticks. on 03:26:836 (2) - on the hard diff, the slider ends on the blue instead of yellow to reverse the polarity to make easier to hit the next objects for newer players
no, it's not landing on yellow ticks, and it doesn't make the difficulty easier/harder to hit even with multi timing.
i know u want to simplify things but this isn't the case on this particular rhythm since multi-bpm on this level are still particular easier to grasp even for newer player depending on how you implementing the pattern. just put 03:27:220 - bpm 112 and 03:28:023 - bpm 98 and you're good to go
since your lowest difficulty are hard, a simple tempo change on this level are okay, you kinda underestimating the player.
but up to u ig
