I don't really want to keep paying Apple every year, but I don't really want to take the game away from users who have paid for it. I believe users will be able to keep the game if they have it on their computer, but Apple will remove it from their servers.

I had a call from Apple today reminding me I have to renew within the next couple of days. Is there any reasonable way around paying Apple, or do I have to continue paying the Apple tax?

This of course motivated me to finish an HTML5 version for this time next year!
