the most impressive thing (i think) I've seen for this game was a 1hp no-hit master mode + hardcore moonlord speedrun, done in 2:06:39 by sbubby on youtube. speedrunning takes an absurd amount of time--as you have to spend countless hours learning the game and its potentially niche strats--so scratch that part off. it already sounds like you've done similar stuff so, i don't know how good of a suggestion this is but still! maybe you'd have a least a bit of a struggle? whether that sounds genuinely difficult and or just annoying depends on your tastes. serious props for what you've already achieved btw
