I think that this would be a really good A Bit remix if you improved the following things:
It’s super quiet, I needed to crank my volume up just to be able to hear the song.
It’s not long enough: trying to fit over 20 songs into 90 seconds must have been pretty difficult, and I think it would have been easier and better-sounding if you had let each song get a little more time (the last few were changing so fast that it honestly just sounded like a mess of melodies for me).
Overall, if you improved those things, this would prolly get a 4.5/5 from me :)
