Block.io

Block.io is a simple io game where you control a player of blocks to make them bigger.

How to play
Collect the blocks scattered around the world to make your block bigger!
The more carefully you collect, the bigger your block will be!
But be careful. The bigger you get, the bigger the blocks will attack you, and if a block bigger than you hits you, the block will be taken away. In particular, if you lose a heart block, you will lose everything.
