The last days I've found more and more pirated versions of Tablet Tower Defense. It is some sort of "out of control" and I can't do anything about it.

That is sad - my current reaction was: I dropped the paid version of nearly every store out there except official market and amazon.

Amazon have their own DRM System, which I use there and for market I will upgrade all paid apps to their licensing sdk (with some sneaky changes to stop hacker kiddies).

I will not offer paid versions on other stores any more. Sorry guys

The amazon DRM and android licensing api are working quite well and un-intrusive (as far as I know) so they should be a small barrier.

If you are a purchaser on any store out there and have any problems because I removed (unpublished) the full version of any game - please let me know so I will solve the issue.

PS: If you downloaded a pirated copy, I am not bad with you (you are not the pirate) :-) But there is a full featured free version available too - use that ;-)
