to reach the last level use 2 chakras(they penetrate all the enemies in their fire range) 2 ultimas and 1 entropyalien, give chakras attack gems, then for the last level use 1 devourer instead of ultima(1 devourer kills 1 juliet)
when i delete the progress the goals that i have reached are not deleted , so when i start a new game i can't finish that goals again and earn some metal for smithing
the new items in the shop can be worse than the old ones ... how can we find full set of armor , or find the best items (crafting of course gives good items but we can't choose what we want , armor or weapon)
i didn't use any advanced units and almost didn't use swordmans! Just upgrade all your mages to maximum level and place equal number of each mage on every stage.
collect some gold , buy "summon lich" ability and find some items that give you "max energy" and "command", the liches will do all the dirty job for you 8)
