Game is way too easy now. Difficulty was fine before, except the randomness of the ice age that would stay through 40 rounds or so. Especially in the beginning. Now it's not even a challenge. I sit on full upgrades everything maxed and have to wait 12 rounds till i can build again.
MAKE IT HARD AGAIN, but not impossible with the random ice age that won't go away lol
for those wondering how to get all stars. Build only mage towers in the fron then in the back 2 soldier barracks for each exit and one cannon. Rest mage towers as said :)
last lvl is tricky, I reset the whole game to try with different upgrades, but then I realized you only need to complete the lvl with one explosive barrel on lvl 12!
Just researched the secret world domination, which seems to be the very last research followed by credits. Got the tower to the 120th floor. Just don't ever upgrade the elevators and your game should not glitch. + this comment to spread the word.
However, sometimes you might be unable to build, which you will be able to after a few working days.
Epic war II was the most epic of all. This one is going back too long hard battles. However the controls are frustrating. Heroes won't react, mana bar is not as awesome and the arrow was one of the most fun things in the second one which I miss:(
