Played this in TF2 Classic, and thought it was ambitious, confusing, but enjoyable with potential. Territory Domination makes clever usage of randomized spawn points and spawn rooms that switch owners mid round, similar to Territory Control (which is not just tc_hydro). This complexity haunts first time experiences because the map makes little effort to guide players anywhere.
One critique I have would be the lack of a neutral color palette, which Hydro uses. Caper appears to rely on exotic colors like purple, green, orange, yellow, dark brown, and even red (a team color) to identify territories. This was baffling in my experience, because as a player I use the walls to identify a team's territory. It was like walking through a rainbow, and in the end I didn't memorize the layout via colors, but by a mental top down view.
I appreciate the letters to mark territories, although on B there were A signs on the wall, confusing me which point I was on. I think they need an arrow to go along the letter to show it is guiding you to there, not claiming this place is that. Gravel Pit C is a good example standing from the tower, I'm not confused which letter point I'm on.
And once all this confusion was gone, and I spent time learning the map, it was like cp_standin with moving spawn rooms. Rounds go quick (sometimes), some rounds end with one team holding 2 points and winning by advantage at time end. And I like the triangle layout, which makes the "mid" fight new each time. You get very little time to assess where you're going though because they are decided as soon as you can move.
Sometimes teams would circle around each other, one caps the neutral point, the other caps that team's first spawn. It could be a tactic, but more likely nobody knew what just happened. There isn't a territory control board to show you which points are initially active either (which is understandably not available).
Overall, I like this map and I want to play more of it because of its novelty and ambition, but it doesn't come across as polished.
