So basically just do the bosses in order. Just add 1-3 bosses so that others can continue the chain. Please arrange them neatly and don't go like "12 goes to the bottom right corner and 13 goes to random places." That would also ruin the purpose of the grid I made.
ADD AN EPILEPSY WARNING IF YOUR BOSS HAS FLASHING LIGHTS Btw add yourself to the list and what you added: emanresu1999 - the project I forgot who made the song remix, but ty Jorel and energypumpkin for the original Final Boss 9
