Pretty nice game! Who doesn't love popping bubbles??

I think it would be cool to have some indication of how many points you're earning during the game rather than having to wait till the end. I also thought I should be able to move at first so I was pressing WASD/arrow keys trying to move the guy around. Maybe a stationary character like an immobile tower would indicate that right away.

I like the menu music! The music in the gameplay was also great quality, atmospheric and relaxing - but felt a little bit like a lullaby after a bit and didn't quite fit the vibe of the game. If you are going the royalty free music route, may i suggest battleofthebits.com - they host chiptunes that are really good for video games and almost everything is under a Creative Commons attribution license!
