Version 1.0.3
[-] Invisible walls improved here and there. Some places to get out of bounds have been kept on purpose.
[-] Fixed the hole in the stairs in World B (kudos to v0rtex for noticing it :-)).
[+] Added a "via ferrata" and a road to the "Goat Pantheon" in World B (after Darky's resolute insistence :-)).
[+] Added a few new secrets and Easter eggs.

Version 1.0.2
[-] Invisible walls improved in all levels.
[-] Changed B2: Carousel to limit some cheesing (certain cheeses are still possible). Also fixed some walls through which the player could be seen by the mines.
[-] Added a shortcut ladder to the area beyond B4: Garden Paradox. It becomes accessible after collecting the sigil.
[+] Added a Paint Bucket item in each level (they are hidden quite well, but if you find them, use them sparingly – otherwise, you will run out of messages to paint really soon :-)).
[+] Added additional persons in Acknowledgements in the first terminal.

Version 1.0.1
[-] Invisible walls improved in Hub World and reworked in World A. No more walkable invisible wall that could be used to skip right to the temple. :-)
[-] Changed the off-screen mechanism used for the lowering fences in B5: The Attic Twins. Hopefully, this will prevent the occasional bug where one or both fences would be already lowered.
[+] Added goats. You will know what then means when you find one. ;-)
[+] Added additional info in the README.

Version 1.0.0
[!] Initial public release containing the Hub World, World A, and World B.
