Epatata, you're correct in your guess.

The developer never really finished the tool. It's a pity because it was off to a good start, never should have been declared a release.

It was pre-alpha at that, missing very critical features -- it didn't even save property flags on your entities and blocks. Alex has dropped it and never picked it back up, never responded to bug reports, never maintained or attempted to maintained any kind of community/feedback. I was beta testing it for him, and it's like -poof-, he's gone. Pity.

I think if he had taken some responsibility with it, it could have been a good tool. I just hope people out there haven't spent their money on it.
