About Synapse Idle
Grow a 3D neural network from a single neuron. Workers haul energy along radiant paths, buildings amplify every passing signal, and a 100-node skill tree reshapes how your synapse evolves. A calm, incremental idle game about watching complexity bloom — tinted in whatever colors you choose.
