It felt too repetitive and tedious to keep my interest. It's just more of the same mechanics without anything new. The basic mechanic of "give up half speed to increase next generator speed" is pretty bad, because it later gives you options like "increase speed of A * n" but what is the point of that, when you're just going to give up half of that speed next time you need to boost the next generator. The automation seems weak as well, with no way to configure the threshold where it triggers, so your early generators still end up too weak and you have to click them manually anyway.
