03:51:966 (1) - Can't really mod anything from this part on, I guess I'm not good enough at mapping for that. What I can say though is that this is hard, but fun to play, and, what's most important, the streams and stacks pretty much all make sense, so you can play it without exactly reading, but following the flow. (I hope I could express what I wanted to say here LOL)
02:19:063 (1,2,3,1,2,3,1,2,3) - This part seems kind of inconsistent. Im you should map 02:20:611 (1,2,3) with the same flow like the two 1-2-3's before
01:18:686 (1,2,3,4,1,2,3,4) - I don't see a reason why the spacing between 3 and 4 here is bigger than at 01:17:137 (1,2,3,4,1,2,3,4) -
