I find the game quite fun, and hard. Hardcore mode is a desperate fight for survival, to the point where I'm actually relieved when the Guardian shows up (meaning the onslaught of regular enemies slows down).

Normal isn't too bad once you get used to it, but I tend to lose focus after a while, and as soon as I lose track of my life bar I die.

My main complaint is that I really wish the electric pulse fired just once when you pushed the button, instead of being a toggle. It's annoying having to constantly double-click it. And does anyone find the laser useful? I don't; energy is much better used on Smart Bombs or electric pulses.
Oh, and the Grand Master achievement is lame.
