In other words, you can't actually do the bulk of the design without a coder -- to me that would be a predicament to extricate myself from, not a benefit to be embraced. I hope (and expect) that it will work out for you, but I feel pretty confident that you could expediate the design process by being able to rustle up and experiment with your own ideas independently.
Give this man a medal. When Dampe 'plays' the game in his head all of those details are being glossed over so of course it feels good.
