Tiled supports editing tile maps in various projections (orthogonal, isometric, hexagonal) and also supports building levels with freely positioned, rotated or scaled images or annotating them with objects of various shapes.
If you are looking for a flexible 2D level editor for your game, be sure to give Tiled a try! Tiled is supported by a wide range of frameworks and remains in active development based on donations!
Free Software
I believe software should be free as in freedom, which means you are free to use Tiled for any purpose, to modify Tiled to your needs and finally to distribute Tiled, as-is or modified, on the same terms.
