I Was Looking At All The Notes For The Game. I See The Game Takes A While To Complete. How Would Someone New To The Game Practice Getting Better? Any Recommendations Would Help Thanks.
If you don't know the game too well, I'd recommend playing it casually, it's plenty fun. You'll learn the map layouts, get used to menuing and just get to know the game. When you're comfortable with the game, get to know the notes, read through them, see if you understand what they want from you. Everything from that point onwards should resolve itself from jumping into the cold water and running the game! :D
There Are Some Things I'm Unsure Of. Why Train Spirit In The Beginning? Do We Not Need Strength?
