The tilemapper looks great.

wait. there is a download link? I must've missed it.

Great ! I can't walk on sand ? :p

No udpate ?

Ok, I didn't understand it was a mountain tile. :p

I think there should be a black outline around the character. it would help visibility, and remain faithful to the original minicraft if you can fit it, that is

I know it'd slow down the tilemapping quite a bit, but maybe there's a way to make the mountains look at lot better by giving them contiguous outlined edges...

The idea would be to check the 8 surrounding tiles to test if they are mountains as well. For each surrounding tile, there would be a sprite to XOR onto a default mountain tile sprite, removing that wall/corner outline from the sprite. How plausible is this?

Here's an example:

(The bottom 8 sprites are supposed to be inverted like that so the XOR removes them)

The top sprite is the default mountain sprite. Before drawing the tile, that would be copied to a temporary memory area. The other tiles would be XOR'd onto the temporary sprite to remove that outline based on surrounding mountain (in order: top-left, top, top-right, left, right, bottom-left, bottom, bottom, bottom-right). The result would look something more like the example I threw together below the sprites.

Obviously it would make it slower, but the question is how much slower?
