Great news!!
Can't wait to play it again, honestly.
you're absolutely right about the upside-down "L" and the sideways "I" as a solution to the letter "T", I have imagined it wrong in my head while writing the comment (BTW I finished the whole game before writing my comment.)
I will definitely return to the game after the update, and I would absolutely love to buy a whole game with that amazing concept.
I wish you all the best of luck in all of your following releases. Keep on making great games <3.
