Size of View Area

Is it possible to increase the width of the view area to grid that is something larger than 24 squares?

You can with the “settings” tab

The settings tab shows a maximum width of 24. Is there any way to increase this to 36?

You can’t make it larger than 24 because it wouldn’t fit in your screen.

If you want to make longer levels. Use the scroll view behavior in your player object. So the screen scrolls when the player moves.
