i think its too easy as you can shoot and recharge the barrels at the same time, maybe if game map was larger and the game was a bit slower paced you could have balanced it a bit more  maybe if the chargeers werent effecively your hp but your means of attacking the enemy and each active charger would give you power ups and if you had none activated youd be easy prey 

Very nice, I like the idea of having to balance repairing the generators with fending off enemies but it felt a bit easy as holding down the mouse emits an endless stream of bullets that annihilate all enemies on screen in an instant and I could repair and exterminate simultaneously. Still it was fun because I never felt like I didn't have something to do. I really enjoyed the music too, it reminded me of the original Terminator movie. With some balancing this could be excessively fun.

Nice game! I like how it felt frantic but not impossible. The music goes well with the hectic gameplay too. I think one possible improvement might be if you could aim with the mouse rather than shooting in the direction that you're moving. Another small update that would go a long way is if you added sound effects. Overall really nice!
