Got an impossible speedrun in a game

this run for 4 years has been considered impossible, and yet, it can be done faster, u just need to be perfect and use a slightly different route, which i gave up on bc even being a pixel further or closer can ruin it, this is the first version, and unlike the latest version, here the boss

  • has less hp (48 hp to 44 hp)
  • is supposed to jump after 3 moves (which via what i assume pixel manipulation and dmg manipulation forces the boss to do 4 attacks)
  • we dont have the corvain slam which was essential for the current version, so its harder to get it
