Worked for me in firefox on windows XP...
I liked Your "tutorial" section with the informative arrow...
I think it's not bad for a first effort, but to me the game lacks focus, you seem to spend most of the time at the far right waiting for another platform, barely feeling threatened by the block bird...
some nice touches showing a sense of humour, the characters eyes looking around for example...
also on my system after dying I had to refresh the browser, to play again as clicking everywhere was fruitless...
will add an irk of mine is having to click to advance when I have just played game with keyboard...
