The Oh No sound that plays with undo has lived rent free in my head for 20years now.

This is exactly the first thing I went for. I cannot believe how immensely gratifying it is to hear that sound once again.

That sound gave me some heavy nostalgia.

I'm not quite as old as the average HN user so I started with I think kidpix 3 which had a wider variety of undo sounds which I can still remember perfectly despite not touching the program for about 14 years.

The voice of Joseph Joestar going "Oh No!" etc. when JJBA became extremely popular totally reminded me of kidpix.

For me it was the "Oops" but same.
