Tech-Gaming applauds the developer, Nitako, for trying something new and not just copying another "swinging game." Unfortunately, they found themselves wanting to put their time elsewhere. They may have been better off adhearing more strictly to the original version. Their best advice is to try the browser game.
If you enjoy it enough to pay $1.99 USD for a mobile version with more levels and simplified physics and graphics, then by all means do so. Rasta Monkey is competent in every way but never quite steps beyond that, offering moderate fun and no replay value.
