Yoo Joonghyuk as a gamer and Kim Dokja as a QA beta tester is really evident in how they navigate the scenarios. Yoo Joonghyuk survives on practice and tenacity. If he keeps replaying the level, eventually, eventually, he will beat it.
Kim Dokja isn't a gamer, though. He's a beta tester. He finds loopholes, flaws, bugs in the system, some obscure forgotten feature he can twist to his advantage. He isn't meant to beat the game. He's meant to break it.
