for what a game is this map editor?

This map editor is not for any game in particular. It can be used for any game for which the content can be described with the primitives provided by Tiled. This includes most tile-based games obviously but levels can also be made of freely placed images. Examples of games that have used Tiled are Shovel Knight, Axiom VergeRoad To Ballhalla and Brigador.
