I like graphs, so this was an enjoyable game for me. A tutorial is nice to have (although not covering all nodes), the visual and sound design are simple yet satisfying.
It is harder to grab and move nodes that are connected. It seems that the edge (running under the node sprite to its center presumably) is consuming the mouse click events, preventing the node from registering this input.
There might be some issues with the scoring. Just by removing different edges and adding them back, I am able to get an additional score even though the graph does not change in the end. Here’s an example of level 1, where I was able to get 500 points:
The Done button does not work for me on levels 2 and 3 for some reason. Didn’t try more levels because the tutorial is not skippable.
Playing the web version BTW.
