You have to deploy a left/right military unit to prevent such a situation. Or you can put a military unit on one side and defend the other with a building or a skill card that damages the enemy.
I'm planning to add a custom key setting later. You'll be able to enjoy the game in a comfortable way.
Thank you for recording the video! I enjoyed watching the video.
When enemy broke to the inner wall, I thought it was pointless to stop it. Even if you defend it, you'll soon be stronger and more enemies.
But I am aware that many users want to do something more in the situation, and I am planning to add something to relieve that desire!
Thank you for your feedback!
