If you beat all 3 bosses in a row you get a new weapon then you can fight the last boss and get a little comic for some lore. Its like not possible to not use the new weapon so i guess you did not make it x) and yeah im thaddeus
Oh then I probably used it without realizing, since I got to see that little ~4 page red comic strip at the end. And congrats on making something so entertaining and successful with just yourself!
