@dingo: Thanks, man!
Porting the games was pretty straightforward. Just had to remake all the .mp3 files as .oggs which only took a minute.
The only other thing I had to deal with was the size of the device. I am testing on the smaller Lumia phone - apparently the most popular Windows phone - and the smaller size was cropping off my HUD elements. So I reprogrammed part of my inventory system and everything was good to go.
As far as sales go, the 3 games plus the bundle have now been on sale for a month. Collectively I have 198 sales so far. I average between 1 and 13 sales a day.
Not sure if that is good, bad, or what can be expected.
The games are all $.99, and the bundle is $1.99
When Corona sent out the email announcing the ability to publish to Windows Phone 8, I ran out and got a cheapo Windows 8 laptop for $299, a Nokia Lumia phone for $69, and a SIM card for $25. CoronaCards is currently free with my Pro subscription.
With CoronaCards being free, I should have no problem breaking even on my investment.
However, when the free trial of CoronaCards runs out, I'll have to see if it is worth it or not to renew.
Everything on Corona's side went smoothly and was super easy to implement, the games play nicely on the fairly underpowered Lumia, but I'm not entirely sure if I can make 500$ a year with my games on the Windows Phone 8 store.
