A major sore spot is that your weapons deplete a energy pool which slowly regenerates energy over time. Can you imagine playing Asteriods, Luftrausers, or Resogun with energy management for your weapons? It's a huge bitch slap to the face and a form of punishment many players will not shallow. It may be an incredible game starting at stage 2 but many people will never see it.
Verdict: Skip it
