:-) We'll keep refining the app based on the feedback we get from users. Currently working on a few stuffs like LiberTweet, but those don't affect my commitment to Sudoku Empire. The multiplayer edition is already ready, but we don't want to push it out yet because it could be confusing for user to grasp the game. We want to release it, when we will have enough user, and when those users will get confort using the single player edition.
