I was unable to find a link to remove a game from the list (in the web interface at least)
Answer
You want to go to view your wishlist: (yours is here)
(not my wishlist)
While viewing your wishlist, you will notice the “Added on” line below the title.
At the end of this line, there is a remove link. Use this remove link to remove an item from your wishlist.
Do note that you need to be logged in to be able to remove iitems from your wishlist.
