The beauty of this is it's simplicity, less is truly more in this case. I'd like to see another one but keep the same formula, maybe with a little more variety with the obstacles. Bugger the story, you're a missile... flying down a tube... that's good enough for me. Also got me all nostalgic as it reminds me of the last level of Shadow of the Empire on N64. Quality stuff, keep it up.
