Thank you for your comment.
The message that we would like to send to player in the 'only one' theme is "how you going to reach the goal while can look at only one perspective at time when another perspective also have an action too".
We would like player to know all information but when come to play, player will need to memorize the information that player can't see visually to combine with what they already see now.
By the way, thank you for point out that our design still ambiguous. We will improve and working more on clarify the message and theme inspired in the next game jam :D
We're very appreciated.
