I am 95% done on my simon game. Feel free to offer any advice or insight. Or just test your skill! It generates the sequence randomly so you should get a different one every time you play :). More interested in hearing about the design as I’m currently pretty weak in the design portion of my projects…
Hey there, pretty awesome looking Simon 
My only suggestion is to make the buttons a little brighter when pushed… mainly the yellow and green active… I keep my screen pretty dark, and when I turned up the brightness I still had trouble seeing it… other than that, really fun! Great work!
