Liked playing this until I had 91 kills and an archer came in from both sides of the screen. Killed one and a spearman came from the other side to back up the archer. Then a swordsman came from the first side before I even made it over to fight the archer and spearman. Badge isn't worth wasting my time to have that happen again.
main weapon is way underpowered. basically works like this... don't shoot, but absorb energy which takes FOREVER and you get up to 5 underpowered additional weapons. die, lose everything, repeat.
