“Walkie Talkie” by Daniel Linssen.

The whole concept is utterly brilliant: “Walkie Talkie” is a small, playable chat system, as all the letters and characters become elements of a platformer level. Think of the letter “o”, for example. Whenever you use it, you will create a rotating enemy contraption which will kill you when you touch it. But if you choose to use angle brackets instead, you will create platformer elements which will help you out to jump a longer distance. There are so many neat things and mechanics to discover for you. >>PLAY
