Oh gosh...um...well that grass is on the water, thats not supposed to be like that lol you need a border around the grass so that it can be on the water. The grass in back of the houses is also a map error, you need to find the right tiles for that. The gym also another error. And the green house looks like it is embedded in the rock because of its background.
@Necro, I finished the tileset, I just need to get some indoor tiles. Then I will give it to someone so that they can insert them and I will then give you the patch.
