As to how it's going, not much to say!
We went from about 300-400 a day to about 10-15 a day. We have no 'marketing' so nobody can really find the game.
I'm both boggled and frustrated as to how to make it a viable market to sustain a business, since the developers are really quite helpless and Apple has all the power to make them successful or fail.
This
test that Popcap did sums it up pretty well.
At least I am able to buy a new iMac with the earnings!
