Looks like a decent engine and some decent art as well. One question I had, from looking at the ground during the snow, was do footprints show themselves in the snow or was it a pre-made pathway texture that was scuffed up ground? Does snow land on any object within the game as long as it has the surface to do so? How deep can the snow get? Perhaps I viewed some of it in a different light and I misinterpreted what was actually occurring.
The scuffed snow in the video is a texture, however snow footprints is planned. They will of course have limitations, but its a nice bit of fluff (they wont be persistant). Snow itself lands on any object in the game that has the relevant shaders applied, and its depth depends on how we write the shader.
Anyway, updated the OP to remove the writer positions, we have plenty of applicants currently being processed so the position will likely be filled.
Cheers,
Dave
