Never tried a Rumble game before, so I downloaded this one. It's surprisingly fun, I normally don't find simple games like this one to be that fun, but I love how frantic and actiony this game is. I had trouble with the first challenge, so I went back to find better Pokemon and somehow ended up capturing a Chestnaught that knows Bite (don't know how likely it is that you can capture bosses this early in the game, but I imagine I must be pretty lucky to have gotten one) and proceeded to mop the floor with everything, even the Mega Alakazam went down in about 10 seconds. The F2P elements are pretty reasonable as far as F2P games go, you need Diamonds to unlock new areas (as well as other things like increased Pokemon , but other than that there aren't a whole lot of limits to this game. So far I have the Leafy, Ember, and Dew Balloons, I'm short 5 Diamonds to unlock the Ruby or Sapphire Balloons so that's about it for today.
