How to get Crowscare's Good End:

 1. Talk to the little bird the first night Ryo enters the forest looking for mushrooms. The little bird appears in 3 different areas in the forest. You must talk to all of them. 
-The first will be waiting in front of the log bridge.
-The second will be near the bottom left corner of the map.
-The third will be next to the mushrooms.

2. When Ryo goes to visit the witch the second night, the little bird will be waiting for him outside the forest. Talk to him again. You should have 4 points for the good end by now and, if you do, there should be a note waiting in front of the torch-bridge puzzle. 

3. When in the witch's house, read the three yellow journals in her library. 

4. When the house is dark and you have entered the trap door, read the fourth yellow book in one of the bookshelves. 

5. When the house is dark, read both notes left in the house. The first will be in front of the red door. The second will be located in the bottom left corner of crate-maze room. 

6. Only when the lantern has been lit in the witch's house, a fifth yellow book will appear in the other bookshelf downstairs. Read it(required), and then add the numbers on the mirror to the numbers on the clock. The numbers on the clock will change after the lantern has been lit. Use the sum of those numbers to unlock the chest in the witch's room. 

7. Before you go to the witch's house on Harvest Night, talk to the little bird in front of the forest once again. If you have gotten all the points above, he should drop a key for you, which will unlock the last locked door and stick you into the good ending!
