There is nothing about this map that says “quantum” to me, or “jam” for that matter. But it’s still a satisfying exploration with the emphasis on verticality, and making good-but-not-great re-use of previously visited areas. I mostly had a good sense of where to go and what to do next, but there was one point when I was a bit lost, only finding the newly avaiable down-elevator after quite a bit of aimless wandering.
It does have one minor but irritating fault: lots of the buttons appear to be pressable multiple times, even though they only take effect the first time. In other words, they are not disabled after being pressed. Although this may sound like quibbling, it’s actually quite misleading as the player tries to understand what’s going on.
Still, I wavered between three and four stars, and decided to go on the generous side despite that failing, just because it’s fun.
By the way, although I found all of the six secrets (which is unusual for me), I still somehow missed six kills, so that I ended on only 113/119. That’s always frustrating.
