The direction where the game goes reminds me of Inward Narrow Crooked Lanes (yay, I remembered the title correctly!) – it has the same surreal, nonsense-language feel. Sadly, as with INCL, I also didn’t quite catch the finer points and didn’t get where it was going.
Happily, though, Hello Wordd goes a little further than INCL in creating a little verisimilitude, and the endings make sense in-universe.
