This seemed almost too slow and obtuse at first, but playing it through totally paid off. There were moments in the middle where learning the timing allowed me to preemptively create blocks that would last just long enough to catch negative emotions while letting positive ones shortly after pass through. I don't know if that was intentional or not but it gives a nice mechanic-based metaphor of recognizing and preparing for negativity as an inevitability, but whether or not you accept it is a preventable choice. I didn't expect it at first, but this game made me think, thank you!
