Just uploaded a new version (1.2.0) to Google Play

Added "Casual Mode" as planned.
(Original difficulty remains as "Hard")

* Whether you win or lose, the life points will automatically be refilled after each battle.

* Enemy wave density is approximately 85% of the original, "Hard", mode.

* No "Game Over" till you beat the game.
(Game progress won't be initialized when you lose a battle)
