I think the enemies are quite good. You have a patroller and ones that look around. I do think there can be more chase focused segments in one area using a combination of the girls.
As for the lewd stuff. I think having a free cam at the end may be nice? Let us observe the girls struggling. This idea isn't worth the coding but I had fun trying to roll the girls around to view them from different angles. Maybe add a bit more to their outfits? I know I had a fantasy of stripping the bunnies down to socks and underwear.
