Tile value V at grid (row, col) draws atlas tile V-1 from the
selected blocksN.pak sheet of your own game files (read in the browser, never uploaded) (32x16 px/tile, 1-based on-disk indices) --
see docs/formats/pak.md and docs/formats/pap.md. Hover a tile to see its raw index.
Entity markers are enemy/item/trigger placements decoded from the level-script .pin
files -- see docs/formats/pin-level-script.md. Most render as their real sprite tile; entities
whose tile-index addressing mode is still unresolved fall back to a colored dot. A meaningful
fraction have unresolved (often negative or off-map) coordinates -- shown as-is, not clipped.
