It's neat. I really wish the programs wouldn't sometimes fail with no explanation. I had an awesome one set up to overclock a bunch of robots, overclock anything near any overclocked ones, and also have them attack nearby ones. But it didn't work. I ended up almost winning and I think I could have if I hadn't had to fiddle around with it and check if it works while under attack.
Also, it feels overly reliant on RNG. You can't win in the higher difficulties without a few powerful nodes that you might just not get.
