99% of this is just the pain in the ass targeting system. So many times I know exactly where I need to hit, but have to take 100 shots to actually hit it.
Challenge 1 just demonstrates how stupid the unit control is. I can't move forward because my units spend all their time attacking goblins that are already dead.
Great concept, completely falls apart in play. I'm constantly matched up against other players with significantly better equipment, the quests are boring and don't give nearly enough reward to be worth while, and the overall pace of the game is way too slow to keep me interested.
2 rounds from finally winning a pvp game and connection to the server reset and I lost. Playing the ai is pointless because you make no money and barely level, pvp is next to impossible because everyone else is ranked hundreds above you and has way better cards. 1/5
The extra height per balloon upgrade just makes the game more difficult since altitude past deep space does you no good.
It need a set objective like reaching the moon.
