Am I violating any of the Solid principles in my demo? Also, are my abstractions adequate?

I wanted to know if I'm violating any solid principles with a quick console based demo I've coded up for demonstration purposes. My main concern is with my player class. I have quite a few methods in the class that do different types of things but they are all related to the player. Is this in any way violating the SRP principle? Also, I wanted to know if my abstractions are somewhat good, is this is my coding style when developing more serious apps.

I have less than a year experience and I'm currently learning all the solid principles and to be honest, I've now became exceedingly paranoid about whether I write good code or not.

Thanks for the help.
