GemTD is still better...
I liked the game, for a flash game it's tops.
It heavily reminds me of GemTD (which I suppose is the inspiration) for this game.
Only flaws? I guess boring towers or something along those lines could be said here... no specials... blah.
It got a little boring, but I liked it.
Throwing gems to 'splode at enemies was a nice fun touch, too =D
In summary, penis.
