very nice. The bosses were easy in many cases. Take the smallest ship and you can virtually sit and shoot unopposed mid screen without getting hit. Just a waiting game for the bosses to die.
needs work. my cells keep sitting there getting killed and will not target invaders even manually. add to that- I keep losing focus of my group when trying to move them across the map. I select the group but when I click to move them i lose the group and they sit there.
balint: to upgrade your students click the student and in the pop-up where you can graduate the student up at the top is "organize Student". click that. I thought it was a label for the pop-up at first too.
not bad. money needs to be balanced. i never bought after the first lvl unless i was purchasing top tier items. when maxed after lvl 8 or so I started to get very bored.
