The games created with this engine can be played either as a point-and-click adventure (using mouse, pointer or your finger) or as a text adventure (using keyboard or any other text input method) and they are totally cross-browser and cross-platform.
So far, I don't know any other engine that works in all web browsers which let users play the same adventure in both modes, point-and-click adventure and text adventure.
It has been tested under BeOS, Linux, NetBSD, OpenBSD, FreeBSD, Windows, Mac OS X, QNX, BlackBerry Tablet OS, Android, iOS and others.
This engine has been used by some other people to create their own adventure.
