Thanks, we appreciate your feedback and Defending is one area where we would be looking to improve.
The Hacker side does tend to provide a bit more of that feedback because success becomes readily apparent. Numbers start going up a lot quicker and spread to other nodes. This is a bit tougher for Defence where your goal is to keep numbers low.
One of the features we weren't able to implement in the timeline is intel gathering which would allow the defending player to slowly build understanding of the attacks being conducted during each wave to better give feedback.
Hope you're willing to give the hacker side a try, and again thank you for trying our game.
