It's Gigawing, man -- it's not so much "charge your shotz" as it is "lol bullet hell? REFLECTOR SHIELD BITCH!"
This mechanic on its own makes it one of the most unique BH shooters out there, and very very addicting to boot. Everyone should play it at least once.
Yeah, everyone's first experience with Giga Wing tends to be, "OMFG this is too much" until you learn it's more "bullet hell judo"...not so much "bullet hell dodging".
When you've got Giga Wing's mechanics down, graduate to the man's game: Mars Matrix. It's the Giga Wings design formula perfected.
