Tileworld is a great game, with lots of features and gameplay. It has a level editor, with a community of people uploading levels for their friends.
This game is owned by 3DG, and SuperJumpBros for programming help.

Tile Planet Inventory is a fork of an OpenProcessing project called "Tileplanetgrass", which was also a fork of "Tileplanetgame".
This game is owned by great24, and was forked to have grass by miniepicness, but has been made in JavaScript by SJB.
