But giving the game-host the freedom to select 30, 45, 60, 75, 90 seconds, or no timer at all, prior to starting a round, just like TWO does, would be perfectly fine here as well. And under that scenario, 60 seconds might be made the default.
Real life is stressful enough without further stressing ourselves with artificial deadlines in this golf game as well. Playing this game should be a pleasurable, relaxing experience.
