Whenever someone gets this problem of thinking that there's a cheater, they instantly start hackusating or reporting. If anyone who hackusates that is reading this, here's a tip. In Cake Wars, try suffocating your opponent and slowly approaching them. If they're hitting you from really far without jumping or hitting you without jumping out of the suffocation, they're cheating. Secondly, If they're blatantly cheating, I'll normally go find a staff member to remove him before he ruins the game for other players.
