I'm no fan of voxel-art, but the t-rex's are super cute XD. The game itself is simple but kind of reminded me of a 3D centipede game at first in a good way. I don't know what tool or method you used, but the map was larger and more detailed then I expected at first. If you can refine your mechanics and use that world-building in an asynchronously-loaded way I could easily see you doing some good level design.
