Looks and sounds great. (I realize that the graphics assets were not created for the project, but they're utilized well and integrated with each other.) Controls are decent.
There is something a little counterintuitive about moving continually to the left, but of course that's just 30 years of videogame cliches speaking, isn't it? :)
Also, I did feel a bit disoriented by being constricted to a single plane of movement when moving through a fully rendered 3D world. This however is a rather small quibble.
