In the past few days, I've spent a significant amount of time further fixing some bugs in the game, including those related to pathfinding, interface switching, and scene details. The specific improvements are as follows:

(1) Fixed some game bugs that affected the player experience. For example, some turrets on high ground couldn't attack properly when monsters couldn't reach them.
(2) Finally, I added the captain character that I've always wanted to include. She/He will tell you the mission for each step.
(3) Added four new maps for Sophia Island. Except for the special maps that require multiple challenges, you can enjoy more battle maps in the early stage of the game.
