After getting through the first level it actually got much easier to get through the rest. It was just getting used to exploiting coyote time (which is very generous) and it was easy to get through the head-hitter jumps after that.
If the theme was anything other than "unlucky" I'd be telling you that the beeps, and the blocks, need some forewarning - however, since the experince was honest to the theme I can't complain!
As a note for next year (hope to see you again) you may want to be careful with effects like blurriness. The colour count is not in your favour there ;)
I enjoyed the challenge of the platforming. Graphics did a good job of giving you clear information. The music was not, as you fear, too irritating - and I kept the sound on until I won.
