The rest of the UI was in the game before this week, so I, unfortunately, did not have any comments for them, although I might as well write some new ones here:

//Yoshikage Kira textbox

//Yes button

//No button

//Player health

//Adam Smasher health that changes colour when shielded

//Gameover text and button

//Win text and button

I think that you should cover everything.
