Bubble popping fun!
It's easy to play as you just have to pop all the bubbles if you save the animals you get more points and even a life if you collect all 8 of them. This is really helpful if you've lost a life either by missing a bubble or popping a bubble with the skull guy called Boomskull. Yeah, don't pop the bubble with the guy who's in black! You have 5 lives but if you review the game you get an extra 2 lives.
It's connected to gamecenter so you have a leader board for the highest score and there are lots of achievements to get.
I find it really relaxing and somehow time just flies by while I'm trying to rack up a high score. Getting all 8 animals I think is key to a high score and sometimes you have to sacrifice a life tapping on the skull guy so you get rid of the bubbles around it. Anyway, it looks simple but to get high scores you really need to work out some sort of strategy...So that's why I wrote difficulty just right.
If you find popping therapeutic and you have a competitive streak like me then I think you are going to like this game.
