Thanks, I'm very glad you liked the tutorial, it actually made up a significant part of development time. I agree the game is easy and I thought about adding more and more components for you to connect, but in the end I didn't have enough time left (might add that in a later version). However, I find the guessing part quite fun as it is sometimes surprising how well this works. You just look at the graph and get a feeling for which nodes to connect, so it actually is part of the intended game play.
