Recently decided to make a Newgrounds account to put songs and maybe other things...
I added my Flashback Introduction remix and my Hotel Mario 2 song, and while I'm at it:
I might as well put a link to my Bandcamp with my album Quantum Tunnel, a Portal 1 & 2 based album, with remixes and original compositions:

And hope you'll find something of interest ^^'
