Too buggy, too big filesize, too simple.
It's not bad. Very simple. But a simple game shouldn't have over 2 MB! Yours takes forever to load!
Then, suddenly, my player won't swing anymore. Huh?
You should add something which makes it more addicting. Walls, for example, or bouncing balls, fireballs, ect. I give it a 6/10, 'cause of the high-quality graphics.
