Not too bad
I was actually somewhat touched by this, because it seemed like you really put your heart into it. Is this based on something that actually happened to you? If so, then I do feel sorry for you. There are always times where our families get into fights and we want to leave. It's something I can certainly associate myself with. I suppose we all have our special place where we want to become secluded, but realize we can't stay there forever.
I thought it was pretty cool how you put a lot of variety of the speed of things going on in the background. I am actually referring to the Newgrounds logo and nothing in the actual cartoon. I know that might sound kind of insulting, but it's still something to take note of. You could probably do better with the animation, as it isn't well defined. I hope everything works out for you.
