Top down shooter where the main goal is to keep a tree alive and help it grow by watering it in a rain of bullets.

Once upon a time, on the far land of Treeia, there was a tree that breathed life into the rest of living things in the land. The inhabitants of the land built a tower around the tree to protect it from any danger. However, when the evil monsters arrived, they managed to get into the tower and destroy most part of the tree. A brave warrior decided that she would give her life to save the land if it was necessary. The tree was still alive, but it needed water to grow back before being completely destroyed. But beware! The tree is dying quickly so you must water it constantly or it will be all in vain...
