This was a pretty cool and unique puzzle experience! I liked the ominous atmosphere and spritework.
It took me quite a while to figure out how this game worked and I think the main issues have been addressed by the others already (how it should show the specific prophecy first so you know which tech tree to aim for, the graph being a little difficult to read in-game, and how the game's a little hard to understand at first).
But it was pretty cool to figure out the game out by the end and it did take me quite a few tries. It was also kinda funny trying to aim for the one specific technology that I needed according to the prophecy, and seeing the silly humans completely aim for the other tech trees instead in the previous runs
