【BeeCluster】My first iPhone app

BeeCluster is my first iPhone app released on June 30.
It's a free top-down shooter.

So far, the download count is not very good especially outside Japan.
So, I have decided to write something related to my iPhone app development in English.
I've been writing my Japanese blog for five months and it contains information possibly interesting to iPhone app developers in other countries, so I'll translate popular posts from my Japanese blog and post it here.
