People seem confused about the UI. You don't need to click, just move. Most keys on the keyboard correspond to a color. Shift + those keys sets the background.

I like it that there's no hint, it just rewards exploration and experimentation.

Launching it on an iPad was a mystery. I assumed it was suffering from the HN hug of death until I tried to swipe back.

Me, too. Thought a script failed to fire on iPad/Safari.

Clicking changes the color too.
