I suggest making two amendments to the rules:
- There is no 30-second timer; there is only "Low," which is only 20 seconds. I suggest using "Medium" - 60 seconds, as you don't have time to think in 20 seconds.
- If a player leaves the game, the remaining player is declared the winner.
- Yes, this is equivalent to an unplayed game, i.e., a technical defeat.
