I like the concept of the game, and will probably devote a post to it, once I have something prototyped. It's still in the early planning stages, but I think I'm onto something.
I've got a high-level design document (no design doc for the game's engine yet). I will be using Torque Game Builder for the game's development. I've been using TGB since it was called T2D and was in Early Adopter mode, and it's come a long way. I think it still lacks a few details for a 2d platform game, but I have yet to create a prototype.
