There had been feedback from our beta testers about how the energy never seemed enough to use for jet-9. Often times, energy would run out for Jet-9 in mid battle, which can really ruin the rhythm of the game.
We changed the mechanics so that now players no longer have to go around hunting for energy! There is no longer energy power up requirements. The only powers you need to collect are the health. Jet-9 has a quick energy regen ability, whereas draco has slow energy regen. They both have basic attacks they can do that do not require energy. More advanced attacks will require energy.
After our beta testing it seems like this is the right direction to go. So we will stick with it!
