Square: Shift squares the box off, Alt flips outline and filled for one drag. Spray keeps puffing while you hold it still, and its Size and Flow sit under the tools. Right drag rubs out with any tool.

To a size. The pixels stay the size they are; the anchor says which part of the picture stays put.

Scale. Nearest neighbour, so pixels stay crisp; whole multiples like 16 → 32 are the clean ones.

Every frame changes together, and one undo takes it all back.

Split sheet into sprites

A sprite a row. Each row that has anything in it becomes one sprite, and the cells along the row become its frames. The game picks a tile's frame from the world, so a row is one terrain type and its variants. A sprite a cell. Every cell that has anything in it becomes its own sprite with one frame. This is for a sheet of unrelated tiles.

Empty cells are skipped, and the sheet itself stays open. Rename what comes out before you save it: the game reads the name.

New tilesheet

An empty picture ruled into cells, ready to draw terrain in.

Cell size px Columns Rows Name

Cells are square here; the grid dialog changes them afterwards. The game reads one PNG a tile, so split the sheet back into sprites before you save.
