I realize that the point of the game is to give the player things to manage, and that the corruption attacks are an aspect of that just as much as curing sick animals is.

But I've played to the available late game twice now, and I generally lose all will to keep going for that session once I start getting a lot of attacks. They're fiddly, you can easily hit your own people by accident, there's no change of side-indicator for if the particular attack instance is about to spawn or has spawned already, and generally it interrupts my train of thought on making some area host more creatures.
I don't want to upgrade my banish because it's easier to accidentally kill my own stuff, but I also want to to make the attacks faster to get back to what I was doing.

It just kills it for me, and makes me want to come back later if at all. However this should not be construed as my saying that anything else about this game has not caused me to binge it for hours at a time, and being sad that I can't unlock all the other stuff not in the demo.

...Okay two other things:
1. You can't complete the "collect a sample" quests for granite and basalt, but it gives them to you anyway. That's annoying and feels bad.
2. I can't complete the "spend 175k in the shop" quest, there's nothing left to buy. I assume this was due to buying things on sale, but uncertain. Also feels bad, especially since if it WAS the sales, then it punishes the player for getting those rn.

I dunno, I started this post going "oh can we have an auto turret function that'd be nice", but I think it'd be far less annoying if the above things were addressed. Also it might be better to just give the keepers a way to slow down the enemies or otherwise help out in ways that aren't just repairing stuff.
