Thank you for the reply! I spent a lot of time on graphics and animations.
Clicks are script + webGL problems. I should have figured out a more convenient way to handle clicks.
For the multiple click, selection box, and army production, more tutorials might let you know these mechanics, I am sorry for that.
I agree with the music :) I tried to find some royalty medieval music and there was not much of them.
Thank you for playing the game!
