One question, do decisions change everything or is the story linear and always the same?
I'm in the part where
an assassin attacks the MC's house and I chose to escape through the window like a rat, so I broke my head falling down and the assassin killed the whole family for sure.
But there was an option
to go out the front door, so I'm sure you could try to fight and save someone even if you don't know martial arts.
Later,
the MC wakes up in a hospital (well known from other games ) and I had that bad feeling, but I don't think I'll go back to make the other choice, at least until I get to a real game over or happy ending.
