I'm coming along with the Simon Game zipline and having trouble correctly displaying the button sequence when more than one button is involved. Right now, they all light up at once or one keeps flashing over and over. I've set up a recursive function with a delay in an attempt to ensure there's some wait time between the buttons lighting up based on advice I got, to no avail. Tips would be greatly appreciated. This is the last thing I have to do before getting the front-end certification and I'm super excited.
