I'm stoked that these levels presented a real challenge! 10 is my personal favorite. Wherever possible, I tried to ensure that the relevant enemy behaviors have been demonstrated prior to putting them into a bigger construction. Ultimately, however, some things just don't match up with our intuition with real physical 3D space. Things like dogs superimposing themselves at the same location and dogs not seeing you if you cross the same axis at a half-tile coordinate during movement. Given more time I would definitely ease the difficulty curve since things go from "oh cute dogs!" to "canine supermax prison" in a heartbeat.
Thanks for giving it a go!
