Hello, I am a new member here and I would ask one question regarding 2D tiled game design.
I am making a MotherLoad inspired digger game and am doing pretty well, but don't know how I should go about one graphical aspect of the game - the borders of the dirt tiles.
This is how the randomly generated level looks now:

(That creeper face was totally not intended.)
The tileset I am using/developing:

And this is how MotherLoad level looks like:

The question is simple, how should I approach round corners on tiles? Alpha blending or some other trickery?
IMO For your patterns – tilemaps, add a border tile to your set of tiles. One tile will be sampled into 4-5 smaller tiles : 4 borders (w/ rounded corners) and 1 center tile. If you intend to have several patterns (grass crossing sand, or grass crossing water, etc.) the more rounded borders collection you have to collect.. ::)
