Personally (apparently like you) I didn’t have any desire to re-play the game, but boy was that first play-through enjoyable! They really did well in making you feel the intended vibe with the visuals, sound effects, bits of dialogue etc
Same experience here. Amazing first run, but it's not really a city-builder you replay constantly, it's more of a solved puzzle game once you finish the run. Definitely worth playing though.
It is a puzzle game. The survival part is so strong you simply can't play it as a sandbox.
