- Load or escape to the spiffy new main menu.
- Select "Load" and choose an existing saved game (directory) that has multiple moves recorded.
- Use the odd computer-chip icon in the upper right corner to access special operations.
- Rename the saved game.
- Select it again, re-access the special operations menu.
- Use the curved-back arrow icon to revert one move.
- Note that there are (apparently) two saved games: one under the new name (latest move), one under the old (previous move).
- Select either, re-access the special operations menu.
- Use the eraser icon to delete the saved game (directory). Poof! (No warning about deleting two or more ...)
- Note that both the old and new saved games are gone!
