I saw your profile and it is apparent that you have perfected the action type of game - very polished submission. Thank you.
The game is very accessible - animated guides, detailed descriptions of icons. Very nicely done! I admit I have much to do in that regard with my games, already implemented a tutorial just waiting for the file upload to be unlocked.
One serious issue I had was that the trigger was delayed - tried with the mouse and with the spacebar but it's the same lag. It made the game a lot harder. Even though the delay itself was more or less consistent so I could somewhat adjust. Still, considering that this is the core loop it's disappointing. Maybe it's just me: running on Chrome.
A couple of minor notes:
The offers by the king/queen are easy to miss. They could be made into a separate window/prompt maybe?
It is very useful that you added a comparison when chosing to replace a guest. However when I left the mouse on the button to select the guest to be replaced a tooltip pops up and clutters the UI.
Good luck!
