I found this website:
The author, Reiner Prokein, wrote ‘All the graphics, textures and meshes are freeware. Even for commercial Games. I just want my name in the Credits in the commercial case: Reiner “Tiles” Prokein. You can modify my graphics in every needed way to fit it to your needs: size, colour, fileformat, etc., you can reuse the textures’
Thanks Reiner for posting these images on the net, they will save me a lot of time which I need to program and do cinematic for the game.
