Gonna request for a mod here. It's.. a different song I think? You don't have to mod if you don't like it. You can PM me on Discord/In-game if you want a M4M.
https://osu.ppy.sh/s/540867As for mapping knowledge, hmm, let's see. I bet you knew this already but sliders are actually extremely lenient. You can get away with half-screen jumps of 1/4 timing if you launch off of a slider end into a circle. A good example is this picture from Shiirn's map of cherry blossoms explode across the dying horizon by sakuraburst:
In this picture the jump from the end of 3 to 4 is huge, but since the slider leniency on ends is really high, the player can be halfway to the next note already and it will still give a 300.
In Shiirn's own words (sorry Shiirn!)
2016-12-27 17:04 Shiirn: there's the built-in OD leniency combined with
2016-12-27 17:04 Shiirn: sliders having a 30 millisecond time delay
2016-12-27 17:04 Shiirn: 02:04:236 - like look at the follow circle here
2016-12-27 17:04 Shiirn: 02:04:268 - then here
2016-12-27 17:04 Shiirn: that's 32 milliseconds,b ut is a handful of pixels apart
2016-12-27 17:04 Shiirn: that difference AGAIN towards the 4 is where the real leneincy STARTS
2016-12-27 17:05 Shiirn: so the player would need to snap from 3 ENTIRELY to 4 in less than 1/4 to actually 100 the first slider
Basically what is being said here is as long as you were in the follow circle 30ms before it hits the end you'll still 300 the slider (I'm pretty sure but don't quote me on this.) This can allow for very demanding flowy to snappy patterns and works well when emphasizing certain sounds.
Yeah that's about all I've got for you. ;w;
