Solitaire One

Though the title may sound like a card game, this Solitaire is an
elimination board game. On a cross-shaped playfield filled with X’es, you must
move a cursor so that it is next to an X, then press the space key to jump
across it. However, the cursor must land in an empty square. By doing so, that
X is eliminated, and the game is clear once only one X remains, preferably in
the middle of the screen.
