Good game but the later levels get to easy. The final mission I won with a physics lab and a super carrier spaceport. The only other strategy I used was spam interceptors which are really strong after the spawn speed and missile upgrade.
the glitch will also mess up the achievement because it will say your total time for the round is however long the last hole took. This is the case for both sets of holes.
there is a glitch that if you open and then close the practice menu, when you have a round in progress, when you continue your round you will be on the last map of the round. When you finish the round you will go to the prize screen and get your cash prize based on how you placed in that round. I have a couple of other things happen instead, like there being more rounds with the number going to -1, but am unsure the conditions that drive them.
rain of arrows is broken. With rain of arrows lvl 2 & mana lvl 2, just use all your mana on rain of arrows attacking their base/hero and you win before they build any troops. Kinda makes the game boring after that point.
