- Auto-prefixing
- Sass
- Undo option
- Have a checkbox ("Safe Mode" or something)
- If Safe Mode is checked, (probably don't worry about actually implementing a checkbox - a hardcoded const will do for now) then when they click on a bomb, it displays only the one bomb that was clicked, and they die
- But, with Safe Mode on, they can either:
- UNDO and continue, or
- END and reveal all the bombs
- Mines that tick down until you uncover more area
- Minesweeper Flags™
- User-specified dimensions
