Horrible
Like others have said before, the gun upgrades make it worse! Taking away the charge to upgrade to something you didn't even know was going to happen is stupid. The accuracy of the burst is horrible even with full accuracy on, does he suffer from some kind of illness where his hands shake violently?
Dying once and bam, it's over... Could at least give the option to continue from the last point...
Too frustrating for it's own good.
