totally awesome, a sequel with more songs will be ideal!
bug report: sometimes i can't scroll pass page 3 of the song book, even though i have 13 or 14 songs, 2 of which incomplete.
unfortunately this games depends too heavily on the repeat speed of the keyboard settings. on my computer (Ubuntu 10.04, Firefox 8, default keyboard settings) it's impossible to push the box onto the "incomplete balloon" on level 18. The repeat speed is so fast that the box just gets lifted by the words, rather than get pushed by it.
Also, this game is too dependent on one's knowledge of specific English words, given veiled hints which are probably dialect-specific.
Conclusion: 2/5 until the problem mentioned above (words lifting rather than pushing box) is solved.
