How do I pause Starseed Pilgrim?

I like being able to pause single-player games like this for when I just want to casually play a game and not worry about keeping constant focus on it. Is there a way to pause Starseed Pilgrim?

Solution 1:

There is no pause button.

Source 1 - The game's Steam discussion forum, where a search for the word pause returns a short list of people asking for a pause button.

Source 2 - This (kinda spoilery) article which mentions: "No pause key becomes a critical issue when working through challenges. The penalty for being distracted with the real world is to lose 10-15 minutes of work."
