Oh, nice catch! I can't believe I never noticed that haha ;;
I'll wait and see if I get any more error reports, then push an update with this fixed a bit later. Thank you!
Thanks for pointing it out, I'll upload a new build with the psd files removed.
As for the supposed album art issue, I can't see any art associated with any of the music files on my end, and no images are present in the bgm folder. Can you email me about this (my email is ebihimes@gmail.com) and send me a screenshot of what it is you're seeing?
