It would be nice if the mod was compatible with other mods like the BuddyEX. I had a challenge in mind where every time I beat a boss, a new character shows up. But sometimes after beating a boss the game just crashes. Still pretty fun though.
I already loved this mod back when it was like 16-23 Bosses, but this new update is outstanding! The fanmade bosses are all pretty cool, the only ones I didn't enjoy were Shadow and Egg Anumis (Latter being from Mystic Realm, go fig) But I know that's not the actual mod's fault. Also, I love the no-hit = Emerald system. It's challenging, but fair which is what I can honestly say about the whole mod. Heh heh, not to brag or anything, but I got good ending first try hyeh hyeh hyeh! Only bosses that felt unfair or too hard were Egg Anumis and Egg Fighter.
