nice game. although i concur that
*rock + paper = scissors
*that whole series of shape manipulation
*sun + moon = apple
*apple + tree = wood
are all a bit farfetched...
the notes are always about 1 second behind the song (the lag is there from the very beginning), a very steady delay which makes the game exactly unplayable. i'm using ubuntu 10.10 with firefox 3.6.
