brain simulation

you are an inventor trying to make the first manmade brain. get nodes into the simulation unlock more nodes and get computation power and money to improve your simulated brain even more! starting from 3 starting nodes from input to output you add nodes to existing layers or make more layers. (inspired by a game i played, deleted,and lost.) how node upgrades work: cost per each new layer 2x cost for each new node 1.33x
