I thought I would get tired of clicking before too long... then I discovered holding down the mouse button. The rhythm of holding to pick up, and then reclicking after collecting all the full grown flowers, is very meditative, and before long I found myself sipping on my tea with one hand while completely in the flow. Picking up a bunch of flowers in one fell swoop is very satisfying, especially with the sound effects.
Both full screen and the non-fullscreen embedded version worked fine for me in chrome on my macbook.
