On my interface i want my user interface to feature a time limit, so you will know how much time you have got to find the scrolls. The interface will also feature the amount of scrolls you have found.
Some user interfaces that i like are:
Left: Call of Duty Ghosts. Right: Battlefield 3
I like these user interfaces because they show what the user has to do, how much of what they have to do has been done, a time limit so the user can know how long they got left and a information section for example in these pictures it shows how many bullets the user has got left.
