This was really great, I would love to see a more developed version of this.
I think the only two pieces of feedback I would give - firsly a lot of the playtime I spent just following the graph and it was rare I could make any meaningful choices. If the game had played through the graph for me, and only let me choose when there was a choice to be made then the battles would have been over a lot quicker, and I could have spent more time developing the graph, which is what I wanted to do more of. Secondly, it would have been interesting to see the enemy's graph ahead of time, so that I could try and design my graph to defeat theirs. That being said, that would change the nature of the game quite a bit, so ... I dunno.
