OK not really. Having spoken on here and doing some digging it looks like i've skipped at least 1 major boss Spoiler: lady butterfly so there's a reason i'm having such a massive problem lol. And i only say first major boss as it;s the first boss (i've fought) that i've had a real problem with (mini bosses aside)
There's a very real chance you've fought some actual bosses i haven't yet!
