The daily review allows you to look back over yesterday's tasks and develop good self-reflection habits. After a day has come to an end, the next time you open To-Do Adventure you will be prompted to confirm whether tasks currently marked incomplete have still yet to be completed. If any have already been completed, simply select "completed" to mark them as such and discover a new block in your land. If you have not yet completed a task, you can select "incomplete" to mark it as such. Doing so will create line-shaped objects on your land, for example cable cars or tunnels.
