Here are a few screenshots of the level editor, when I was doing map e01m10

I’m pretty sure I will make it public when its done, it’s not very user friendly (you have to know all the keyboard shortcuts), but it does a good job 🙂

What you can see :

• Exterior environment generation using perlin noise, water and external walls placement
• Room walls placement
• Floor
• Room details
• Sprites and markups
• And finally the properties editor (with a small, easy to use, scripting engine)
