Alright. You should go for an arrows keys/WASD and mouse clicking for shooting. If you're adept at triggers. This could be a pretty badass game. I'm not going to bash on anything as it says it's a demo. But it has potential. I'm more of an RTS/RPG kind of guy. What kind of things did you want my help for?
That looks very nice, but the textures are huge (256x256 x4) and animations are very poor.
Thank you very much for sending it though, i will use it for reference as to how i will build the mesh! That mesh looked pretty great.
