Ok, way to difficult – Galaxy Defense Plus: Classic defense game Review

I love defense games and this one started good, until mission 9. I have played other games that as the missions got harder you had the ability to upgrade you defense outside of game play. I also noticed that at time the enemy would roll past turrets without taking a single shot. Could be better with some tweaking, for now deleting it.
