Here are some quotes of MSP on the Dark Castle Facebook page linked earlier:
Thinking about controls for DC on the iPhone. The game is an action puzzle solver but with two handfuls of controls how do we make the jump and keep the soul?
Nice bump in people today! I am digging up the original art I did in the 80's to make the game. Trying to hunt down Jonathan Gay (programmer) as well.
The level editor does need to be finished. We got to a beta state but never got to finalize with ZScculpt. The team at SHFF who is likely to do the iPhone version is a seperate resource.
We have a bunch of stories developed for a 3D version. Right now the iPhone intrigues me most. Thinking about an auto run that you tap the destination. Finger strokes for the rock direction.
It's interesting to hear his stance on the iPhone version, along with the level editor. The fact that he brought up future Dark Castle games gives me hope for the future. :)
My advice is to join up, perhaps we will find out more in the coming days!
