Very solid all-around entry. My only complaint is that it took me a little while to figure out the discrepancy between the screen wrapping and the DNA areas; went extinct several times by flying past the goal. If the map scrolled and you could explore islands and continents, with a little bit of species progression, I could play this for a very long time.
NOTE: If you get the missing dll error, install the x86 version of the runtime instead of the x64 as the author suggested.
