Your code is almost correct. But a turtle's xcor will hardly ever exactly equal round mouse-xcor, unless the turtle happens to be standing on a patch center. If your turtles aren't dying, that's probably why.

Adding some more rounding should make it work:

if mouse-down? [
  ask turtles with [round xcor = round mouse-xcor and round ycor = round mouse-ycor] [
    die
  ]
]

But note that it's actually easier to take advantage of the patch grid than to use round. The following code does the same thing without explicit rounding:

if mouse-down? [
  ask turtles-on patch mouse-xcor mouse-ycor [
    die
  ]
]

Depending on how you want your game to work, you might also consider ignoring the patch boundaries as a basis for determining what turtle was clicked, and just compute the actual distance of the turtle from the click point:

if mouse-down? [
  ask turtles with [distancexy mouse-xcor mouse-ycor < 0.5] [
    die
  ]
]

The 0.5 here is arbitrary; you could adjust it up or down to control the sensitivity.
