Hi, thank you so much for playing my game!
The crows eat crops, so if you let them build up, then crops you take too long to get back to will be eaten and thus, you will fail to get any score from them.
In the interest of doing better in the future, would you mind answering these questions for me:
Can you elaborate on the feeling you had of not knowing what was happening? Any opinions on what would have helped you not feel this way?
Had you looked at the "How To" screen? If so, what was your general opinion of it (helpful, not helpful, etc), and how did it influence your understanding of the game?
What did you think about the length of the gameplay time?
