This is quite a decent variation on the popular word game Boggle™ by Hasbro®, the only problem I have--and this is a small one considering that the software is offered free and has such a small footprint!--is that it doesn't have a consistent dictionary (recognizes "but" not "buts", "mute" but not "mutes"). A better option would be to offer an editable dictionary option so the developer, who is offering the game for free, doesn't have to spend the tedium of having to create or add to a dictionary.
