GREAT GAME!!!
Wonderfull game.I like the cartoons and stuff like that.But things in the game are too expensive.
As for the jewels,try using Blue sapphire instead of Blue Pearl.Yes, scientificly,sapphires might not be blue.but sometimes they are.It should have been the Yellow Topaz as the thunder element.Anyways wind is not so fun so why not put Pearl and Diamond as specials??
I like the colourful cartoon.The music is not so distracting and also matches the cartoon.So nice job on that!
Anyways the game is huge and far better then any tower defence game(or mushroom defence game, haha)i've ever seen.ANd i wish i could put my own gem(BGW).
Good luck and keep it going dude!
