Any feedback would be great :/
Sure.
music choice is upbeat and catchy right off the bat, great choice on its own i think
intro text could be tightened up to be a bit shorter, slightly
transitions are fine, although later on a few of them were a hair longer than i'd like because i think it interrupted the flow slightly (this is a minor point)
most importantly, your video sized poorly: it looks like your video was captured/exported as like 960x720 or something and then rendered into 640:480.
here is an unstretched 640x480 video (correct for standard definition)

here is a 640x480 video stretched to be 810x480, losing its original 4:3 aspect ratio

note the difference of the thickness of the black bars on the sides of the video (youtube automatically fills in part of those boxes depending on the size of the video).
slow-mo effects were nice... not bad.
maybe add credits, or a description in the info. there was no way to know who's playing or where these clips are from, which would be helpful.
i don't normally comment on clip quality but you could cut out some of those clips in favor of showcasing only your most entertaining or notable ones.
not bad, keep producing.
