Roguelike

Tried to incorporate more Roguelike elements into the game.

In Roguelike mode:

- Players will build their army by continuously choosing from three random options.

- With each castle upgrade, players will get a chance to choose from three random options.

- When a player's soldiers die, they will respawn after a certain period of time.
