The angel investors on the moon makes completely no sense. Simple math, 50 angels should boost the production by 100%, which is 2x the previous amount, but IG 1 million angels makes almost no difference, maybe 1-10%...
To xXMarineSniperXx: The story about Trojan and Greek war is about the last 50 days of the wars 10th year. And Achilles died soon after he killed Hector, prince of Troy, the main defender, and soon after that, Troy fell because of the wooden horse. And you know the rest ;)
Mine ballons don't work properly. You can see the enemy simply go through them and they don't explode.
Anyway, Quite easy game, specially when mine balloons cover the whole screen :D
