Zwan feels more like a experience than a game, you navigate a decaying world and discover the works of the artist Hieronymus Bosch hidden in it.  The game feels similar to Proteus, in that the joy is in exploring the beautifully realised audio and visual world.

The main idea is to give life to Bosch’s paintings, while enacting a metaphor of pain and madness.  If you collide with certain obstacles, you’ll inflict more pain on yourself, and the world will slowly become more dangerous and wicked, until eventually you reach Hell.  It’s a beautiful experience, with an excellent soundtrack, well worth checking out.
