Interest in Portal 2 like 3D level editor?

Hello, I have made a level editor very similar to the one in Portal 2. Currently it is only possible to extrude walls and toggle the materials of the walls, but I would be willing to add more features like placeable items, etc if more were needed to make it a better sell. Would anyone be at all interested in this? Would anyone consider purchasing it for $5? Here is a link to the Portal 2 editor: https://www.youtube.com/watch?v=Eg7OMGwxrCs

Thanks.

yes if you made more features, you can sell more than 5.

Yes of-course if this will be avaliable on Unity3d this will be something special , and you can sell it for more than 5$

Idea: See if you can get this to save/load levels at run time, so end users can make mods/custom maps and the like. I really wish unity games had mod support…

i would but this if it was like a elder scrolls Construction set

Ok, now I know this is a bump for an extremely old thread, but I was just reminded that I never published my code for a portal 2 style level editor while all of it is (mostly) working. My question, two years later, remains – would people still have interest in such an asset? My current editor would allow for wall extrusion, object placement, rotation and level saving. Would people still have a use for this? Not sure if something else exists on the app store now which would make my tool not quite as unique as it might have been two years ago.
