Not my favourite JPal map, but it's still a JPal map. So it's a solid, fun map with the usual hallmarks: great visuals and impressive attention to detail when... detailing (ha) combined with the smooth flow of their more recent offerings. I think some of the corridors could have had more interesting fights (corner Shamblers don't count), but the good fights generally made up for the one-dimensional incidental/traversal combat.
It also has a really fun ending that's very satisfying and feels like a proper climax to the action (unlike jpqm12). Enjoyable stuff overall.
