$5 dollars or not...
...I can't see why anyone would pay for this. Not that it's particularly bad, but the Internet is rife with well designed platformers with prettier graphics and more creative gameplay for free. And frankly playing this just felt like a painfully slow version of Sonic the Hedgehog. Pretty decent, but there's just no reason to play when you can just whip out the old SNES and play 'Super Mario World' for the hundredth time.
