Firstly, great game. Catchy music, nice art and satisfying gameplay if you get a nice combo.
Anyway I found a weird glitch when I fight the librarian in gallery mode. After the match the background changes to the office and if I do a rematch I fight the accountant. (with the librarian coming back out after the fight.)
It's not really a big deal but I thought I'd mention it in case it causes further issues down the line
