It's my homemade editor which I used to create maze in the game "Infestation". It is written in C# The first working title of the game was "Space Rescue" and it can be still seen in the editor. Click on rooms representing boxes to change the room colour and bewteen them to set/unset room connections. The buttons describtions are in Polish, just like comments in the code The button meanings: Wynik - Result Zapisz - Save Wczytaj - Load You can load the file Mapa into the editor.
