I really like the idea of the game. It took me quite a bit to realize that click-and-drag moves while click-then-click makes a connection. I feel like that'd be better as left click vs right click since I kept accidentally picking up nodes even once I realized what was wrong. Another note is the blank spaces for nodes that show up even when the nodes aren't able to be used is pretty confusing. The mechanics are neat. I hope if you expand on this in the future you consider color blind players.
