I should be ashamed of myself, totally forgetting to update the news here. I promise to do better coming times...
Anyhow. Version 0.91 has been released with a small patch. TetraGems now keeps track of high-scores of you and the top 20 players of the world. With this release of TetraGems, I also updated the webplayer again (that one was still version 0.71 :s )
Full patch notes can be viewed on the Google Play store.
