your money should regenerate slowly automatically when you are idle (no troops killing enemies) because if you run out, theres pretty much no doubt that you are dead.
bug: every time you launch the game and load your game, once you win the next battle it says "congratulations you have won a new race" yet there are no more races.
morale should be affected by how much ground you have (the more ground, the better morale) because that makes sense; if you have more ground, your men feel more confident. I was 2 steps away from winning by taking the area, and then I lose from morale.
heavy weapons have a good feel, theres a good variety of builds, although the story doesn't make much sense (nations can't survive with no lower class people, and if the Spectres had so few resources that alot of them died of starvation on the new planet, how could they possibly gain the resources to build an army more advanced than us?) and its way too short. 3/5
normal is too easy, but nightmare is both challenging and fun... some advice: if you ever get trapped in a huge crowd of enemies, simply drop an undead mine; they are cheap and powerful and will destroy everything around you, giving you a good breather.
loli had 4 missle towers and 3 fully upgraded tackshooters firing on the MOAB, plus i was dropping pineapple grenades to explode right on it, and it didnt turn into smaller bloons till the very end and i was out of money.
