I got the game with the bundle and really enjoyed it! Manouvering cells around is fun and the puzzle aspect have some depth that made you think fast.
Would be really nice to have online highscores for it :)
Thx so much.
We added online score when we had a service allowing us to do so 'easily'. So the Android (with Google play) and Steam version have it.
This version without any DRM or mandatory account unfortunately is not, but you're right, it's part of the fun to compare your high score with your friends, or the world.
