I acquired the Hero6 source code about two years ago, just before the Cole's announced Hero-U (School for Heroes at the time). It collected virtual dust until last week when I started inspecting the game code. The game looks to be 80-90% complete with most of the artwork already rendered (my weak spot). In my spare time, I've started finishing the game. I'm not sure how long this will take, but I suppose the amount of time will be equivalent to my attention to detail.
I just thought I'd post something here in case someone had already taken steps toward finishing the game. I'd love to hear back from anyone interested in assisting. The dissolution of the Hero6 forums was a major resource loss, but the remaining information still available should be enough.
All contributions are welcome and appreciated! If there's enough interest, I'll start posting progress updates.
Here is a quick run-through of the initial game play. Follow the cursor to see what I'm pointing out. Also, watch for the pink shadows of sprite-doom when I move diagonally - fun stuff!
