Nice! Also, could you make them a bit bigger? The full creation. Because when I use them, they are too small and don't fit the full screen. Only half.
And could you make a tile set of a small town/city? If you have ever played or heard of EarthBound, (Mother 2 In Japan) you'd know that the main location in that game is Onett. A small town. Something like that would be nice. But it's just a suggestion. :)
