BlockIt

Game is offline F2P rage/arcade game. (You can buy only ads disable)
It's hard enough to give you hours of fun and easy enough to make you feel your progress.
You can compare your skill with friends and share with them your replays.
It's my first game so don't expect fancy graphic but nice game-play.
(Game is in sort of beta so some things don't work such as video recording/sharing and IAP)

Please be aware that if you have epilepsy, this game can be dangerous for you
else Have Fun.
(you will be fine)

If you have any issue or expansion idea please write is down in comments below.
Please don't mind multi-device/user achievement glitches.
[Works well on my nexus 4 (5.1.2)]
