there is a bug where you can bug crystals and stones. sometimes the potion lady sell them and when she does, you click and drag it onto inventory. Do not double click to buy. exit shop and talk to her again and the crystal and stone is refreshed. Bought 5 stone of blessing this way before i ran out of gold.
90% of my storm attack is done by helicopter. as the enemy base gets damages, it recharges the storm bar, so if you can get enough helicopter units in, it is like spamming non-stop. however if the enemy storm charges the caterpillar, you have to do the same.
best units are the tank, the missile launcher, the caterpillar and the helicopter. Use the helicopter and worm when the storm charges. helicopter with so many units can get in some damage so when you reach final attack, even if it ends up as a stalemate, you will have won becasue you did some dmg in the end.
cant finish the 3rd mission either. the houses wont evolve further, and like others said, diostribution of resources is uneven, dont even know how much is enough
