It's an incremental but not really an idle game. Interesting idea, kinda short though. Getting to $1M is fairly easy, but there's no actual content after that.
I think it would be much more useful if dragging an enemy changed its position (placing it before or after the other one) instead of swapping it with the target enemy. At the moment it's very difficult to place an enemy at the end of the list or to exclude it from the list completely
It does not die only when the mouse is on "run"
