From the developer:
The fastest way to alter all the games is to use the 'Global Game Speed' slider (displayed near the top of the main screen). This control can be used to quickly adjust the speed of all 30 games (up to 90% slower). It's great for experimenting with the settings for all the games or for quickly adjusting the settings of all games for a new player.
