THERE IS A SITE WHERE I CAN GET SOME TILESETS?

Try actually detailing what you need in the body of your post, okay? People aren't likely to respond in detail unless you ask in detail. What kind of style is the Witches House? What kind of tiles are you after? A certain type of area? Any particular kinds of tiles you need and if so, what? What engine are you using?

Now, having played the game myself, I can tell you that the base resources of that game were, I believe, Mack tiles. The site they were hosted on went down, unfortunately, but if you look in the resource section (where this topic should have been put, by the way) there's a topic where people have posted some of those tiles for the sake of keeping them around. That said - a lot of the base material is Mack, yes, but a lot of editing and custom content was done by the creator in the case of the spookier tiles, so they probably won't be around.

Check the resource section here, though, since I know that some people have posted some tiles that might fit your needs. (Under the Development Header).
