A lot more changes tho, including some structural, design changes.
Secrets added, that you can collect, and discover Secret Planets! Pulp Planets rough version. Secret Planets rough version.
Dark Vignette when nearing death.
Tons of debugging.
And a Game Concepts page added.. with a mention that it contains spoilers and you shouldn't read it! The game is minimal and simple enough for anyone to discover on their own.. but if it just seems too Alien.. now there is a page explaining with human words.
