Great game!
I don't get the low scoring reviews or that this great game doesn't have more than 134 reviews yet, counting with mine. The concept isn't something new but there was pulled much effort in into it.
It's seems that I have remind some of you people that this is not your average "5-minutes-Newgrounds-game" that you finish with a "Well, that was fun, but too easy blabla, make moar ^__^" bullshitreview. This is something you can enjoy for hours. There is a lot of varity in the game modes, better than in the first gem-craft.
The quality is great. Graphic and engine wise. Why are people complaining about the graphic so much?? There aren't any big flaws in general and the new addictions compared to the original gem-craft are huge!
It's a true tower defense game and if YOUR attention span only lasts for your "average" NG games, then sorry...this isn't something for you then. Though don't blame this submission for your ignorance. This game is challenging, fun and most of all, a real time killer. Complains about this game beeing "too hard buhuu ;(" are mindless and show that some of don't want or can't handle games where you have to THINK for a minute.
Overall, an excellent sequel!
