Super cool little strategy game...
First game like it that I played. Pretty addicting gameplay. Its pace was perfect, as per difficulty, and who doesn't love to push that little suicidal self-destruct button, followed by a comical barrage of "Oh no!" as they all blow up.
The learning curve can get pretty frustrating at times, but its also what makes it a really good game.
The Bottom Line
A great puzzle-game. You'll be playing this one for hours. Variation in levels and play is good, and the pace is just right to lure you in with.
