You seem a little upset. I'm not going to read all that though, it's just too much. Just take a break when you get frustrated or lower the difficulty. Also, you can experiment in training mode or watch a bot match to get a basic understanding of a character.
I didn't make this to frustrate you I want you to have fun with it.
That's because if you remap buttons in match you don't get the option to save. But you can go to options and save before leaving the game. I hope this helps.
