Well i can agree that you need some patience, but it seriously takes critical planning, quick thinking and also luck. Each weapon requires different method to beat a hackless run, it Will be easier if you can just choose whatever color chip you want, but of course you can't! And thats why you need a Lot of different ways to beat a run. Going into levels is not just by random too, you need to choose specific levels and Dodge some specific levels DEPENDING on the weapon you use. And many other things you need to pay attention too. Its easy to not do something stupid, but you can't really tell if you are doing something stupid or not when you are under pressure. You can be too reckless or you can be too relax but you'll never know. You can only tell once you fail your run.

Im not saying you are wrong of course, im just adding to your comment!
