Hey there, thanks for the re-purchase!
Can't believe there's so many people here who remember the game, considering it never sold all that well : P
It did have an editor! All the games share a common engine (custom direct-x thing). Unfortunately the UI-heavy editors (Cubology had one too) developed enough issues during an update a few years back, that I decided to remove the menu link. Never thought anyone would notice!
If you *really* want to see the editor, let me know and I'll take a look into it : )
