Well, I'll admit I have a bad habit creating a hard game. But if you know the pattern and what to do, you could easily beat them (I can beat the game in 27 minutes casually, but I am cursed with developer knowledge). There is also Harold fight after that, and I think that one is harder than the TML+Guards fight.
TBH I'm quite sad that you didn't finish the game. Maybe I'll put easy mode or something similar for my next game.
Anyway, thank you for playing!
