>>20042171Apparently controller to most people is preferable. I play with KB&M. The game isn't built for it, though. All your button prompts will be in controller buttons because Miyazaki hates PC games.
>>20042192Fighting bosses is the big point of the game. Most bosses will whoop your ass for the first few tries until you understand their moveset (unless you're gotten really good at the game by the time you go up against them or if they're an early game boss).
I'm sorry you had a rough experience and ragequit when you tried the game. Other people enjoy the struggle, feeling of overcoming odds, and refined gameplay.
