I've been flip-flopping about having powerups in the main game mode (as opposed to only having them in the faster paced 'arcade' game mode) and I thought I'd settled on them being in both .. and then my son comes along this morning and insists the main game mode shouldn't have powerups because that's not like how Berzerk plays. Now I'm in total crisis! Flip-flop flip-flop flip-flop flippety flipping flippy floppy flipping arrrgggghhhhh! Who's the designer? Me. Not him. But maybe he has a point..
