Hi Marko -- huge thanks for flagging the website bugs/quirks. This was updated some time back and hasn't been updated in line with developments to the game. This will all be sorted this week.
And no - some of the features listed in the latest post are only available in the full game.
I really appreciate your comments and commitment to solving some of the puzzles here. If you drop me a line (jamin[at]superstring[dot]studio I'd like to make sure you're rewarded at launch - your flagging of issues is genuinely very helpful!
