I'll do the indirect approach then if he's listening.
First of, it's great to hear someone is working so hard to make the game more fun. I and a lot of fans thank him for that.
Second, I'd just like to add that the first V6 version that he made available, even though it has progression stopping bugs, the alien AI is great there. Fast, dodges the bullets and goes straight towards you. The latest V6 version that a few people are testing and from their streams I've seen so far, the aliens have become weak again. They jump around and use the walls and ceilings beautifully, but they at least seem a bit slower to me and they spend too much time retreating from the player. I really like their behavior in the first V6 version (too bad it breaks the game in many places, the later revisions are fixing the issues), so I just hope he makes a variety of difficulty choices for the aliens' behavior similar to how he had different stats for aliens in his V5.
