WordMix Pro arrived in the Google Play Store. While WordMix will stay free of charge, selling a pro-version will support the developing of the game and helpkeeping the free version adfree. So far the Pro version does not have much to offer but some more background images for the game. I do not intend to make the gameplay differ between the free and the payed version.
A 3D OpenGL interface for the game is under development and will be available in the pro-version soon.
Check out the first screenshot:
