is this game dead"?
No, I wouldn't say so. I have a major version 2.0 release that is in development right now, and it is taking a long time to re-create the game from the ground up all over again.
The development of this release is currently on hold due to my college work and other small side projects I am working on. I last worked on this game about a month ago and plan on picking it back up in the summer!
