Thank you so much. Totally agree. All improvements noted. Diagonals were a bit tricky to work out how to make selections function correctly. So I stuck to the simple up/down left/right to meet the deadline. 1-2-3 runs are in, but locked to the symbol type, but I found myself wanting those across symbol runs too, so that will definitely be added.
Audio is a few old Sonic Pi scripts I wrote a few years ago.. not very good.
And the commend about the time limit aspect. Yeah, I think you are right, count down taken very literally! :p
Thank you so much for commenting!!
