Wow, I haven't been following it so closely but I'm way more interested in Into the Breach after hearing that.
How it works is that your enemies telegraph their action, you react to their turn, and then they perform their telegraphed actions. Each enemy type has predictable moves with detailed outcomes, as does every action, so you know exactly how much damage you will do, how your attack with push or pull or damage an enemy, etc
You also know the order of events that will occur during a turn (ie environmental damage first, then fire, etc) so for example, if an enemy is on fire and only has one health left, you don't even have to worry about its attack because fire damage always occurs before enemy actions.
The combat is less about dealing damage and more about positioning; pretty much all your attacks push or pull enemies a certain amount of spaces. Some only move enemies and don't deal damage. This is important because 1) enemies can damage eachother so pushing enemies so they can hurt eachother is a major tactic and 2) it's a mech vs kaiju game and protecting buildings is more important than protecting your mechs. Pushing an enemy so its projected attack arc hits your own mech instead of building is also a common tactic. Pushing enemies into other enemies does damage too, so it's also like that mobile roguelike Auro as well
