Kinda hard, but fun.
I love this game, it's so addicting! However, there is a glitch. In the challenge where you fight Nene, P-bot, and Salad Fingers as Samurai Asshole, you only have to survive 2 minutes to win. I watched the clock and survived 4 minutes, yet I failed the challenge.
Good game overall, but there needs to be Dad from Dad 'n Me in there somewhere :)
