great game. i had to go back and flawless hardcore all the levels besides the last level just for fun, theres no way in hell i could ever flawless that one. for the people with lag i too have lag even on my 1060 card, for the ones that are saying they dont they are bs'ng you. i seem to only really get it when theres multiple bosses on screen and when they are using special shots, like the exploder types, thats really the only big issue for me for obtaining the last medal, im sure i could do it with no lag. all in all a great game.
