That's definitely something that could be explored. The big issue is that the longer the sequence becomes, the more likely it is that the player will just have to use some kind of method to record it, like screen recording, or writing it down. I don't particularly think that that is very interesting gameplay. I like where your head is at, though, and I'll think on it and see what I come up with :)
And thankyou for the kind words! I'm so glad you're enjoying it, and happy to exceed expectations! You are mostly correct, it is almost a solo project, I've had some help from some people, and from the great discord community that's formed around the game, so I can't take all the credit :) And you are right, I'm not asking for anything. Donations are welcomed and very appreciated, but in no way expected or requested (:
