The panning was not intentional, there's something strange with my file because I had not added any panning at all.. Hoping to find out what went wrong.
Yeah I agree the tracks could be more tightly knit together, writing in a short period is very new to me so it was enough just to focus on this without considering everything as well haha.
As for the theme the "title screen" track is actually nearly identical played backwards, the other one however has just a small element of mirroring in the bass part of the beginning.
Thanks for your feedback!
