Sad to see people discontinued the game because of the only puzzle existing in game though. But from my perspective whenever a puzzle had only a few button activation that lights up or dim down, it doesn't need knowledge anymore. Pretty sure it's just a simple trial and error game with sequence.
As for the pigpen cipher, I don't think anyone with a sane mind would remember that shit in their head these days.
And I would like to suggest dev making the choice to skip puzzle available even for first play through. Yes, in case anyone wondering, the puzzles can be skipped with choice after clearing it once.
It's almost like half the players that stuck at the puzzle and the other half don't even bother mentioning it. One thing I'm certain of those who solved it on play doesn't remember shit about pigpen cipher nor the song lyrics. It was simply because an opened browser behind the running game
.
It literally took like 5 seconds to look through the table that pop up when you google pigpen cipher, and another second to see the word Carcosa when google 1 phrase from the song.
