I am entering a video game design competition in which I must submit a game with a few requirements. The judges have 10 minutes to play and review the game. My team and I are making a military tactics game like Frozen Synapse or XCOM (although it will be real-time). I was concerned that with such a game, the judge may choose to play it slowly and carefully which may mean that he or she will not finish many levels before the 10 minutes is up. What are mechanics that I can use to force the player to keep playing at a reasonable speed? I've already thought of using a round timer which I'm not sure if I'll implement.
