An isometric pixel art world on a real Aseprite tilemap
First a tile kit on a small island, then a whole continent: beaches, forests, a highland lake whose river drops over a waterfall, roads with stairs and a bridge, a village, a castle and a port.

What makes it work
Inside the file
- Aseprite tilemaps are square, so the 32×16 diamonds sit on a 16×8 quarter grid.
- The terrain is a real Aseprite tileset painted with set_tile_cells, and stays editable.
- Water shimmers and the waterfall falls by swapping tiles between frames.
How it was built
Step by step
- Tile kitAn 18×18-diamond island with every piece: water, beach, grass, farmland, roads, cliffs, a waterfall.
- Generate the continentLayered noise, a river that runs downhill, roads that cross cliffs only by stairs.
- Paint the tilemapCut into 16×8 cells, de-duplicated into a tileset, painted onto a tilemap layer.

How it was checked
- Every build step matches the design exactly.
- The flyover camera moves over the real exported frames and never draws the world itself.

Walk into the picture
A golden-hour valley as 19 depth planes in one Aseprite file. Each layer stores its distance in its name, and the camera walks into the painting.
