awesome!
loving this one, it's like a tetris spin off almost, but the objective is the opposite, try to block lines isntead of make them, cool idea.
game plays well and is pretty fun once you figure out the concept, if not for the login stuff i'd give 10 stars instead of 8.
still could use a little more though to be perfect, more block types maybe... or be able to earn the ability to save a specific block for later somehow, but still a lot of fun. :)
4/5 vote and 8/10 stars.
