Once I went to the settings and disabled the timer the game was very chill and fun to play. It reminds me a lot of an old game I used to play that required drawing roads between buildings and meeting throughput requirements.
Were the drawn pathways supposed to not be allowed to cross? I'm not sure if something went wrong or what, but I was allowed to cross them all I wanted and could otherwise still progress to new circles. I played without taking advantage of it (for the most part).
I also hit an issue with the tutorial text getting stuck on the screen which made it difficult to see orbs in the top/center area.
