I like the blocky characters and the style you used for the terrain. The music fit in well too, but you are absolutely right about the sound effects. They were way too loud and got obnoxious to the point where I pretty much turned the sound off. Using the mouse buttons to move and attack would sometimes cause issues with my web browser, even in full screen mode. I'm not sure if it's something specific to Opera, but sometimes when I would click both buttons one after the other it would open a new tab or close the tab I was playing the game in. Regardless, it's a cute game and I enjoyed it.
