A relatively complete platform tile set for Sympathy, a 2D puzzle platformer in the early stages of development. Follow Sympathy's progress and learn more at the Sympathy development blog on Tumblr.
Thanks so much! I'm working on a few more tile sets and hopefully I'll have some backgrounds in the works shortly. Also, if you're interested in game development at all, I may CC license my tiles and other assets in the future, so they'll be available for other people to use them.
