To anyone who cares. There's long since been a 'pseudo' remake of Mitadake called Misuterii high. The Tv tropes is pretty outdated, but the game itself tends to dip in and out of being dead and alive.
It's fairly faithful to Mita, with some additions including a pretty good list of actually not trash user made modes.
Like the guy above me, here's the discord to the Misuterii (Which is quite frankly much more alive then that graveyard.)https://discord.gg/Tqn43VJ
