I'm listening to the song on loop, downloaded from the ZIP file on itch, and it sounds fine to me but maybe something else is happening in the engine? If you like, you're welcome to bounce it into an audio editor like Audacity and lower the volume of the intro if you prefer that.

I just thought I'd let you know, the problem I was having with your tracks looping (making a cut off sound in between loops), wasn't your fault. It is a problem in GDevelop, the game engine I was using. I opened audacity and looped your tracks and they were as smooth as butter, no cut offs. I fixed the problem in GDevelop by choosing "play a sound on a channel" option, instead of "play a music file on a channel" and it loops beautifully. Just in case there are other GDevelop users, this may help. Thanks again!
