While arcade-style shooters don’t necessarily need to have a great deal of variety in order to be interesting I’d say the rule would be the simpler your game systems are the more flavor you’ll need to include in order to sustain interest. Void Gore has the simplistic systems down, featuring a vanilla shooting attack, a small variety of potential power-ups, and a zone shield that works on a cooldown and will both wipe out enemy fire and damage enemies within its slowly-growing area. Unfortunately, for the most part, the game from there is all about trying to eke out more points and survive longer while facing pretty well the “same general enemies but harder” until you stop. It’s not terrible but it also really fails to do much to distinguish itself, even at its low-budget price.
