it's pretty good but upgrades quickly run out and you are left with boring repetition with little change. needs moar upgrades and energy should recharge faster(with an upgrade) and recharge between waves
you need to allow resizing, this is flash after all (it is vector based, hi) currently zooming in does not increase the size of the game , and pressing show all bugs the view completely because you have it shoved into this little box for some unknown reason....
Awesome Game! I agree that you need velocity and persistance for bullets as well as helicopter shots, they should aim at the ground but do a small area of affect. the helicopter missiles disappear when the target they were shooting at is killed. also, the hatred ability should have an animation so that you can know it is working, something like enemies catching on fire randomly perhaps. Good effort, keep suggestions in mind for update. 4/5! =)
