In this micro-work, you are a dinosaur of unspecified type, standing in a featureless plain you can't leave. A few turns from the start, you will be killed as a result of a massive asteroid impact nearby.
As near as I can tell after several "playthroughs", this is all that happens -- all that can happen. It would probably take about as long to recreate this game in Inform 7 as it did to write this review.
