I've had some truly epic moments playing with Shiny Rock Codes. Like the time I found a code that gave me a rare item, and I was able to use it to beat a level I'd been stuck on for ages. Or the time I redeemed a code and got a ton of in-game currency, and I was able to buy all the stuff I needed to upgrade my character.
These moments are what make the game so addictive. You'll want to keep playing, keep searching for codes, and keep redeeming them to see what kind of awesome stuff you can get. And with new codes being added all the time, the replay value is huge.
