Artstyle? Marvelous. Humor? With a cherry on top. Fun? Higher than Mont Blanc. Performance of the final boss on low-end hardware? Uhhhh... Let's not mention that. The cutscenes honestly save the game, but looking at the fact that you just have to press E to kill anything (without counting that one bacteria at the end of hallway that noclipped be through the wall and you can't kill it for some reason) the RPG is not needed. There also are issues with the camera. But I saved the fucking president.
