Angry Birds Seasons debuted with a Halloween theme, complete with pumpkins, bats, dangling lanterns, a full moon, and spooky trees; this installment offered 45 levels. Soon afterward, the "Season's Greetings" Christmas-themed pack added 25 more. Even though the inclusion of snow and presents everywhere was nice, I found the physics for the Season's Greetings pack to be a bit lacking.

While it's certainly fun to have more levels, after flinging hundreds of birds the gameplay starts to get a bit repetitive. You find yourself yearning for new, vastly different birds that can do new things.

Another issue is the number of ads. Now, I am a big proponent of developers' getting paid for their hard work, and I think both the paid-app and ad-based models are good, but in this title it feels as if Rovio is taking things a bit far. At the start of every turn, a small banner ad displays in the upper left. That seems a little much to me, but it isn't over the top. What does feel like too much, though, is that every four turns or so a full-screen video ad displays, interrupting your game. You can skip past it, but it's still somewhat annoying.

Overall, Angry Birds Seasons is a fun game, as the original Angry Birds was, and I appreciate having more levels. However, more levels is all it really offers. I'd like to see some more innovation from the Rovio team for the next release.
