8x Gold Mine
3x Crystal Mine
3x Iron Mine
1x Kamikaze
10x Fresh Skeleton(weakest unit)
That pretty much wins every mach in less than 4 mins, by making the enemy suicide by killing the skeletons.
Quite a nice game, but dont get me wrong, i finished it and everything, but the thingy with bosses is, longer time spent killing it doesnt necessarily means more challenging...spending 15 minutes at that last boss moving the mouse in circles around the screen was kind of annoying and almost made me give up....
