There are no instructions, you just have to start playing. It is incredibly addicting, and although there are no yeti (plural of yeti is yeti?) or penguins, and the sound effects aren't quite as fun, it does have monkeys, coin, upgrades, strategy, and balloon popping.
i mean really, how much more fun could you cram into a game?
I would bet that if you begin playing this game, as you try to figure out what the heck is going on, and begin to be successful, you'll all the sudden look up and it will be dark outside - unless it was dark out when you started playing, in which case... well you know. Playing this game is kind of like reading a Dan Brown book - the chapters are really short so you think "well, just one more chapter" and then all the sudden you have read the whole book. In this game, the levels take between 20 second and 1 minute so you always think 'just one more'...
Sorry to give you a time waster, but really i think we all need to waste a little time now and then - especially at midnight on Thursday apparently.
