Zooming out
Some games require you to zoom out using the keybind Ctrl + minus (-). For example, My Pet Rock requires this because you can't see at the very top without zooming out, making it impossible to put the rock to sleep. Another example is Rock-Kit, which when playing 2-player, the second player's jump scrolls up the screen unless you zoom out.
Refresh Rate
Some games go faster/slower depending on your refresh rate. For the intended experience, please manually limit your refresh rate to 60Hz.
