Reminds me of Dynamic Sword Skills a bit, honestly. Largely in the sense that it uses Ocarina of Time style Z Targeting, in that you lock on to a target and can then circle around it or switch targets to something else. I've been using DSS and Battlegear 2 to help make combat a bit more variable to some success, though it's made it rather difficult to play without those two mods in that I absolutely despise vanilla combat, to the point that I've long considered just going Peaceful with one of those mods that allows you a method to get mob drops.
Well yah if the mobs were the ones doing the targeting. It's the pufferfish things that are targeting you like that.
