Note for version 2.0.4

By default, the maximum map size is limited to 500 cells in width and 250 cells in height. If you need a larger map, download the source code, locate scripts/editor.py, and modify lines 406–411:

if new_w > 500:
    self.console._print("Width cannot exceed 500 cells", "error")
    return
if new_h > 250:
    self.console._print("Height cannot exceed 250 cells", "error")
    return

After changing the limits, you can either run the source directly via main.py or recompile the executable using PyInstaller:

pip install pyinstaller
pyinstaller --onefile --windowed --add-data "assets;assets" main.py
