Short and sweet. Looks great too. Congrats on the submission

Like others have said, there needs to be some obstacle or otherwise more challenge. Cool to see box2d and physics in use, though

Interesting! Great mood and concept, but without some obstacles to overcome about the game is extremely straight forward. 

On a minor note, it seems the collision point for clicking on the nodes is slightly off up and to the left compared to where the sprite is drawn.

I liked the color choice and the dithering effect on the background. I'm curious to see how more intricate game mechanics can emerge from this, but as a chill game it does its work well.
