Nice game, outstanding soundtrack!
I'm not great in any of these physics games, but as far as I see it "More Happy Bees" has a smooth gameplay and a fair level of difficulty, so it's fun to play.
Like others mentioned before, the music of this game is just great, and I really mean it. Even if you don't play the game, just start it and listen to the jazzy tune, I promise it will cheer you up :-D
