I made an (ios) arcade game that is rather unconventional, and as a result many people wont exactly know what to do or what the controls are when they first open it. As a results I have had to add a rectangular "Tutorial" button on my main menu screen so that when I hand it to people, or other people hand it to people (etc) its all ok. FYI: When the game first opens it does go to a tutorial, I just wanted it to be accessible for repeats if necessary
In the original build I designed all the buttons and had labels on them, however the artist inside of me says that doesn't look good, so I had a friend redesign them.
The new buttons are bi-colored and very minimalist (usually with the outline of a shape in them). We came up with simbols that work for "return", "play", and "leaderboard" that work... however we can not come up with one for "tutorial".
What would be a clear symbol that could be put on a "tutorial" button?
