It would be nice if the bullets you fire were not the same color as the ones being fired at you. It would also be helpful to know how far along you are in a level, and more so how much life a boss has left.
Hopefully badges aren't a consideration until the unevenness/pure luck aspect of Destiny mode is fixed. I hope to never feel the urge to play this game again until I know that I might actually stand a chance of accomplishing a level. I have lost at 3:15 more than ten times with nothing but fully upgrades units. What's the point?
For the past few days I can not get past the WIX screen before a flash crash. As much as I enjoy your jazzy little tune, I wish I could place a negative vote.
