I really enjoy these types of games, just started playing this and my first impressions are WOW what a simple idea, the game play is neat and graphics are nice. The first few levels are relatively easy to complete but the complexity increases gradually as you get more familiar with the rules. I'm playing mostly on Bird Brain skill level, Almost Human is a step up and is much more challenging which make this game worth coming back to. Given there are 60 levels I think this is a game I will be playing for sometime. I have a few friends who also play this and it's fun to compare our scores on the leader board, definitely gives it a more competitive feel.
