I'm sorry, this is really really poor.
Yes, it's kinda playable, but there are so many things wrong with it. Graphics are terrible and gaudy. What's with the flashing colours on the reset button and paddle and bricks? The colour choices are bad, and the whole thing looks rendered in low resolution, which is strange considering the total file size. Dressing up the levels in some kind of tropical theme is a nice idea, but not well implemented.
There is nothing 'musical' about this game, despite the title. There's a background music track (too soft), and some sfx when you hit a brick, that's it. It's a standard, yet poorly executed brick breaker game.
Gameplay: ah, I can overlook the cosmetic issues, but this really breaks the game. First, the ball can get stuck between the paddle and the bottom layer of tiles. What's the idea with that bottom layer anyway? Besides, the ball always bounces off at a fixed angle off the paddle, which means that so long as you always catch the ball with the paddle, the ball will follow the EXACT same trajectory each level. That's lame. Unless, of course, you want to hazard the risk of the ball bugging out by letting it bounce off the bottom tile layer, which is also quite lame. The standard way around this is to let the position at which the ball hits the paddle influence its exit angle in some way.
The way I look at it, your priorities for your next update are completely off. More bricks and paddles are just bling. They're meaningless unless you fix the fundamental issues first.
