As of right now the only bosses not included and the reasons why are:

Rotgut, Wormwood, Hornfel, Great Gideon - due to incompatibilities with Boss Rush

Tuff Twins, The Shell - Since I personally found having unlimited access to bombs from Bomb Grimaces trivialised some bosses (Might bring them back if people want to)

Singe and Raglich - Bosses that have attacks that leave pits, ended up bringing balancing issues (Might also bring back)
