I figured it out after a couple runs — this game is fun! I like the way you have to chart everything out ahead of time if you want to pay it all off. The node-like structure felt very soothing on my mathematician brain.
Yay math brains! Thanks for playing! I'm sure some tutorials would be a welcome addition in such an interface heavy game. So, I especially appreciate that you stuck with it and had fun after figuring it out :D
