The "pay rent or lose" mechanics here are super cool. I love how the escalating decrement forces you to transfer out of early game synergies or else get buried. For example, I thought the "lowest becomes 6" would be super strong until I saw that I was losing 4 pips on every decay. At that point, I wish I had placed more aggressive growth options to keep up.
This game also does a fantastic job of giving the player lots of agency, even in the face of random roulette spins. I found myself experiencing the benefits (or consequences) of where I had placed some node several turns back. After a few build cycles, it really matters if you can construct a chain of "next" nodes to your desired target without clobbering some other synergistic piece.
The whole setup is very cerebral down to the nebulous synth vibes in the background. I actually kind of like the minimal visual style in this case. It does everything it needs to.
Very cool. Great work!
