At first I was hooked by the detailed hand-made artworks, the possibility to write your own story, and the all-pervading symbolism.
Then I discovered how easily (and selectively!) this "game" creates networks of kindred spirits.
I suppose this is its main feature.
I traded pieces of my true self with my character, with other characters and with the people behind them.
Most of the times, it was a valuable and teaching experience. So yeah, a game?
