`TileMap` tiles are now saved by replacing a sequence of empty tiles (ex. "0 0 0 0 0") with a single negative number, the absolute value of which preserves the amount of sequential empty tiles (ex. "-5"). Examples: "0 0 0 0 0 0 45 3 0 0" -> "-6 45 3 -2" "0 0 0 0 0 43 0 0 0 0 12 0 0 0" -> "-5 43 -4 12 -3" Results from re-saving some levels from "The Crystal Catacombs": "The Journey Begins Again": 409.2KiB -> 40KiB "Fjord of Fortitude": 319.1KiB -> 65.4KiB "A Light in the Darkness": 613.3KiB -> 301.5KiB "Light and Magic": 456KiB -> 173KiB
