Hello BuildingWolf100, Changed3D is built for the Windows OS, PC.
This is a dilemma, either I tune down the difficulty of the boss for the sake of the players who can't beat it, or leave it as is for the sake of difficulty and faithfulness of the original game.
There is a better alternative that I think will be best. I will in the near future implement the "Simple difficulty", which will be selectable at the start of a new game, and will tune the difficulty of most of the enemies and parts of the game, and obviously have a unique early ending when reaching a certain part of the adventure.
I'm sorry that you are struggling with the boss! After I finish with the ServerArea segment, I will design this Difficulty system.
