Misery mode isn't actually there yet, sorry. What's there is... sort of a crappy placeholder.
There wasn't even remotely close to enough time to finish the horrid thing by the game's release; so the placeholder was put in. The problem: with the rest of the game, it's been more of a team effort, numerous people working on it at any given time. Hard mode was a little different, as all of the new stuff and balancing... with some exceptions... are my doing, BUT, there were also plenty of testers to try it. But Misery mode? Nope. I'm the only one that can make it, and I'm the only one that can test it. The difficulty is just too high. So doing this is SLOW. I think, though, that it should be ready to go... finally... within the next month. It *might* come with the next update. Maybe.
What I can do though is show a couple of videos, examples of some of the upgraded bosses:

https://www.youtube.com/watch?v=6cGOkBPd1owThe Warden's third and fourth patterns probably need to be tougher, as does Crystal Mother's first one; I'll likely change those up a bit. Also, Crystal Mother, that third pattern has this giant green wall thing constantly fired at you, but the bloody recording software, for no apparent reason, makes it nearly invisible. You can BARELY see some flickering of the thing every now and then. But if you're wondering what makes that pattern so bad and why I seem to be rushing through it, that's why.
Misery mode will be a bit different than the other modes. Normal, Hard, and those beneath them need to appeal to lots of different players, and feel balanced, fair, and fun above all else.
Misery mode though? No such rules! Oh, it'll be TECHNICALLY fair, as there wont be any genuinely undodgable attacks, but... you can say the same about the fight against Queen Larsa in Mushihime Futari's Ultra difficulty, and THAT nightmare is the single most difficult boss ever made. This mode is inspired by stuff like that. I was told to make it so hard that I could barely beat it myself. Instead of "make it fun for the player" it's more like Cave's hardest stuff, where it's more like me actively trying to make sure the player does not win.
The bosses may also get an additional line of defense too; preventing their patterns from being "bypassed" by overpowered builds on that specific difficulty. I haven't decided on this bit yet. It is cruel.
So yeah, it's not ready yet. But that's fine... it's the sort of thing that'll take ALOT of practice to even get started with. I said that Hard mode is "for those that have mastered normal mode". Misery mode isn't like that: it's for those that have mastered the genre. The bullet-hell genre, that is. Or at least, that's how I intend on it being.
So yeah, that's... that.
But anyway, congrats on the Hard mode win. The mode is aptly named, and lots of players don't get all that far into it, getting stuck for quite awhile. It's a good accomplishment to beat it. The question is, can you CONSISTENTLY beat it? It'll get harder with the update.
Good luck on future runs, and again, if you should run into any problems whatsoever, please let us know here. I play this mode a lot myself, and I'm FAIRLY sure there's no major outstanding issues.... but I could have missed stuff.
