Fairy follows a mouse movement. Cannot pass along a wall. When Fairy touches a snake, game is over. Take Fairy to the flower garden. 妖精はマウスカーソルに向かって進みます。 かべは通れません。 へびにさわるとゲームオーバーです。 妖精を花畑に連れて行ってください。
Changed the code. Using more DRY and native glide. Changed the game controls. Now you should MOVE your mouse in the direction you want the fairy to go.
