I'm torn about it, there's a lot I like about the idea and the game so far. It's got a fancy 2D normal mapped lighting system that I haven't seen in many other games. And the controls and player physics are pretty refined, with help from some people on TigSource. My 3D modeling and animation work was a bit less crappy than my previous work.
It probably looks too much like Metroid in it's current stage though - verging on copyright infringement. The tiles I created were for engine testing, based on the original Metroid's "Brinstar" area, and I hadn't gotten around to adding new ones.
So - this build is where I left off, at about the 5 month mark. There's defintiely potential, but it's pretty sparse and not a cohesive game yet. My old XNA tools were bogging me down, making progress really slow - redoing it in my C++ engine would be a huge boost.
