Maybe it's because I'm using Chrome, or some other reason, but this game lags horrifically, rendering it unplayable. The lag started in the Green levels, and have been continuing through the Yellow levels. It is impossible to time jumps with the lag. This game would be great if the lag wasn't present. I enjoyed it very much up until the lag started up. I turned off the sound, music, and changed the quality to low in hopes of fixing the lag, but it doesn't go away.
