Well I'm just on the first screen with the color combining stuff, and this is pretty neat as idle games go! I'm a pretty easy mark when it comes to these tbh lol
The thing that would really put this over the top for me personally would probably be being able to move the different nodes around and connect them myself, and being able to visually see the resources being sent between each node. Very few idle games do this, but making what amounts to an interactive screen saver is really just absolute catnip for me! The only idle game I've found that actually does that is probably Factoryidle though so I'm not saying this is a huge exclusion or anything. Plus it would probably be extremely difficult to implement given how static the game is at the moment!
