Good point. It is not (yet) a game. More a game mechanics exploration. That's what I was able to do in restricted time (I only had part of the four days available).
But the initial goal is to expand as long as possible. Restricted by number of blue you are able to collect. These appear at "difficult" parts. BUT balancing in the jam version is just ... I am happy that there is any balancing, as I had some larger bugs towards the end.
