Is this enough to buy my soul back please? /s

Great idea! Taking the power of my enemy seems like the main hook of the game, and I'd consider it the strength of the game as well! I can imagine targeting certain enemy types just so I can use their attack against another type that's weak to it. I think you could address an area of friction I had, which is how loud the (epic) music was, by adding a volume slider. Good work so far :)
