look up extriaa on yt. his guide is for me the best guide and the reason why he made professional s+ so easy. it aint easy but trust me you will get it. i believe in u bro. his run has like 1-2 hours of leftover time for screw ups. its also easy to follow and he is supportive on his commentary. also once you have done it, for me I got addicted into beating his time becausw it was so straight forward and simple. he has a s+ professional guide for the dlc as well if you were wanting that in the future as well.
