What makes GrowCastle so great.

If you are not familiar with the game GrowCastle, then you will find some information on this post. GrowCastle is a tower defense game that has simple graphics, yet it explodes with color and action. You receive one Archer and three Hero's, you are able to buy more Hero's and Archers as you progress through the game. Each and every Hero comes with a special ability and passive skill. The Tower is the thing you must protect from monster's, -as they will proceed to attack it in every wave you pass- you must protect it and upgrade the Tower for more HP and MP. The more you use your Hero's skills the more MP you consume, which is another thing you get when you upgrade your Tower. There are much more thing's like dragons, Hell,colonies, etc. And sadly, this is where i finish. Tell me how i did on my first post.
