Great fun! Reminds me of the original. But it is stuck at level 580. Game will not advance to the next level. Have deleted and reloaded the game, to no avail. Have notified developers, but I am still waiting on a solution. Also, sometimes the graphics will cover a pig, leaving me to wonder what I missed in the attack. Also, the fly in graphics during play make it impossible to see where your bird is when.you need to tap the screen to drop a bomb, inflate or shoot a snot.
