Here's a Mystic Square remake made by NooblyPerson, the same guy who made Death Angel's Dream (HRtP STG reimagining). This game actually came out before DAD, but it still seems to have insane hard danmaku just like in the sequel.
On the bright side, this game vomits bombs at you, so a clear isn't hard at all. I actually managed to clear this game blind, but I wanted a better run to show off, so that's why I did another credit for this video lol.
It's funny how the most infamous part of the original Mystic Square is actually one of the more reasonable parts of this remake, Yumeko seems to be a simple boss to LNN once you figure out her attacks. I was actually considering going for LNB (since it actually seems possible unlike in DAD), but I realized that there's too much nonsense in this game to the point where it would actually take a significant amount od effort to achieve such a run... maybe someday in the future... maybe.
