This game rules!
It reminds me of good ol' fashioned Worms.You should add a way to cancel your move if you've started drawing the line already. Also the accuracy upgrades are not necessary.If you were to make the upgrades simply increase the length of the guide line that would be awesome.Furthermore I really wish movement around planets would be an absolute right = counter-clockwise, left = clockwise instead of whatever it is now.All in all it's an excellent game.Keep up the good work.
TIP:To get lots of money buy a lot of units(all if you can) and max their HP.After every match you get money from the remaining HP of your units. :3
