Hey! Thanks for your feedback :D
The balance is well tested, you have to make the right decisions to get to the next levels. Different choices lead to different stories in the end. We implemented 14 different endings to this game, which means you could figure out many different approaches :) To get past level 2 you have to make the right decisions. Not every unit will solve your problem/plague from the stage before ;)
The chaos meter in the top left corner should not be filled, otherwise you're game over.
