Making levels and modifications

Has anyone tried creating their own levels or modifications for casual games? Which games support such features?

Hi. I've tried creating my own levels in some casual games, but Subway Surfers, which I play on subway surfers free , doesn't support modding. However, it's so addictive and dynamic that it doesn't even require it. If you're looking for a game where you can create something of your own, it might be worth trying other projects, but Subway Surfers remains a great choice.
