Ah I see, I think I just played it too much myself and I didn't realize the first drone would be quite tough for someone who never tried it before :)
What? No! I'm awesome at games and it was SO easy... Ok, I died a couple of times. :P
I think it was the fact I so frequently found my shields were depleted because there was no time for a recharge between shots. Yeah, balancing your own game which you've played over and over can be a nightmare, and you're almost certainly not going to please everyone whatever you do.
