Meh....
Well, it certainly does 'poke' fun at the situation, ha ha ha! But seriously, it's only good the first or second time around. After about a few minutes, it gets old fast. And the puke has very little use in the early going, and with it's odd aiming, it makes it very hard to hit anything when the birds get heavy.
You could try adding a few more levels with new music and obstacles in each, as well as refining the puke aim. It could be great, it just needs some work. I might even make it has a good footnote in NG history, as someone else here has said.
