I'll keep my comment very short as I don't know if you even read our comments as you don't provide feedback to us nor bother to even 'like' our comments. Pretty easy level.
When I see a level that remakes one of the 50, I start by going back to the original and playing it first. Then I play the update and try to evaluate if the additions/changes add anything. In this case, I don't see that the ZRs/R added all that much. It felt like Martin could have put them in at first and then thought to himself ... "You know, I don't really need the extra bots here." Which may just be a fancy way of saying that sometimes, less is indeed more.
