If you really want the game but can't find it elsewhere, you can get it from here. Note, though, that the dl speed is really atrocious. I'll have to find a way to get it hosted somewhere else. >_>;; <_<;;
Edit: And actually, it was supposed to run a full week but due to a lot of negative feedback that Hero6 received, we decided to yank it. I didn't really expect people to start blasting us, right and left. Oh well!
