So now that the tutorial is out of the way, it's time to go out and do some hero stuff! Except not at the beach. Not yet, anyway. The beach should NOT be the first level you go for, as that's the devs trying to elongate the game. No, the first level is actually Forbidden Jungle.
Why? Well multiple reasons. First, this is where you unlock one of the levels, Misty Island, by doing a minigame. Second, this is where you unlock the blue eco vents that are blocked up for some reason. And third, this is where your first boss fight is. Among other things, this is where you SHOULD start.
