believe it or not, this is actually correct.
right now, it is 100% impossible to lose zone 1, even if you are playing the worst game of your life. In a sense, it acts as a "learn the ropes" level that is intended to be very forgiving for new players. (but don't tell the new players! :d)
at the same time, i think experienced players will still find zone 1 to be one of the most important levels to perform well on: It offers a massive bounty of easy points if you can take advantage of the slopes/birds and get up to 5x happiness quickly!
I'm honestly still shocked to see so many companies sticking to 2-year commitment contracts. The way mobile technology is moving right now, i'd almost be afraid to sign a 6-month contract!
Unity's a pretty cool engine, but it's not something i'm really planning on diving into for a little while, and certainly not for games like these. The next thing i'll be learning is objective c, but i couldn't say for sure when that will be.
