Hi, I'm one of the creator of the simple arcade game called Icetris. Today we've released another version of our game with redesigned tutorial. We've gained some feedback for previous versions that tutorial was not clear. Please download our game and tell us here what do you think about the tutorial and the game in general? We appreciate any feedback! The game is free - you can grab it on Google Play (http://goo.gl/MLWaTL). Older versions for iPhone is available on the AppStore and we have version for Windows Phone too - get it. Thanks in advance!
