This is definitely a very good game, I must admit. However, there are a couple of things you could tweak a little. The hitboxes are a little iffy occasionally, ending when it looks like the ball hasn't hit you at all. Also, no matter where you click on the player image, it always seems to go up and to the left, which gets annoying occasionally. However, everything else seems to be fine. Classic arcade style stuff is always good. Well done.
Just thought it would be a good idea to tell you that you should probably sort out the tab button. It allows you to cycle through all the objects in a given area. Or was that on purpose? I'm not sure. Anyway, just warning you if you didn't know.
