I really enjoyed playing it, apart from stage 3 which had a ridiculously spammy corner.
I really didn't like how blue had all of the height advantage in stage one, but because of that, it meant that it was red who had to work really hard to win rather than blue, which is an interesting twist for the map.
Consider opening up a little bit more of height to red for them to access, and definitely do something about spawncamping of red on stage 1. Blue found a way to sneak behind red, and get height advantage when spawncamping, which sucked
