From the creator of The Tiny Box.

You play as Tilentia, a druid who has been living in the woods for all her life. Lately, you've noticed that the Tree of Ritus, the spirit of the forest, has begun to wilt because of a mysterious sickness. Since you're bound to Ritus, you're affected by the disease as well.
Is there a cure for this illness? Find out before it's too late!

This map contains:

• A creative alternative to crafting;
• Three endings (one "bad" and two "good", so to speak);
• A loyal wolf companion.

This is a single-player map; it won't work with more than one player.
