Finished this one and quite liked it! Couple more thoughts:

The penalty for dying is great. There's a 3-second cutscene, you lose a minute from your current run's remaining time, and then you just respawn right where you were. Substantial but not obnoxious.

It's nothing so extensive as the endless new quips in Hades, but the game does a solid job of interspersing little bits of story and dialogue between runs. There are even a few brief flashback levels that show up to fill in the backstory of the protagonist.

The nonlinear world design is smartly layered so that you've always got several goals of different sizes you're working toward and not just wandering aimlessly. There's a couple big world-spanning puzzles that are always simmering in the back of your head. Each region of the map has medium-size puzzles that cover that whole region. And then you're constantly encountering fun little one-off puzzles and platforming challenges to nab treasures as you travel between your objectives.
