Glad you liked it and thanks for the feedback! The intro sequence was handled by Unities Player-Prefs which are annoyingly persistent (also, I wasn't expecting anyone to want to see that again Lol).
While the symbols are random, there are some things behind the scenes to keep the rng from being too bad so it's not as big a factor as you'd think unless you're trying to get Really high scores.
Also, I'll put the slides from the into in the game page if you want to see them.
