Originally I had an idea for a game that combined a classic game with a modern twist. The classic game was minesweeper and the modern twist was making it into a platformer/digger game.

Here is my initial design for MineSweeper:

The idea was that the user would move around and dig the selected block until they reached the "cure" or win object hidden somewhere in the ground, as with true minesweeper style a mine or "virus bomb" would go off if the wrong block was chosen.
