The idea of building tension with a looming, ominous object in the sky is quite interesting. The downside is that it clips through the collision geometry, which immediately breaks immersion. The oppressive music does a great job of enhancing the atmosphere. I really liked the time rewind mechanic with the route repeating itself—it's a fascinating concept. Perhaps just minutes and seconds on the asteroid would be enough; I feel like displaying milliseconds there is a bit overkill. Also, maybe the cards shouldn't have been rotated, as it's hard to tell what card it is when viewed edge-on.
