I was really looking forward to this, however after coming across the first boss, the entire game died. It's unfair what you have to go through with that thing. It moves so close to your turret defending its own shots, when you can finally start hitting them, it's too late.
I wouldn't mind it so much if there was more of a fighting chance, but I'm unable to progress, because of this spam tactic it keeps doing. The boss's energy shots have so much health when they stack on top of each other, my turret can't blast them away; specially if the boss is directly on top moving with the energy shots. How am I supposed to continue onwards? I like difficulty; but I feel there is an issue regarding how the boss's energy shots own Hit points.
