The button for deleting saved games is in a bad place. As soon as I click on the file I want to load, my learned behavior from playing video games for so many years is to click on the button right below the selection window. That, of course, causes the game I wanted to load to be deleted.
This button is in a bad place, compared to the play button, which is at the bottom of the screen. I suggest moving the delete button farther away from the selection window, and adding a confirmation dialogue, so that people won't be accidentally deleting saved games so easily.
