[TOMT] iOS puzzle game, ~2018-2020, minimalist isometric-ish ball-rolling puzzle with red/blue triggers

I'm trying to track down a premium-feeling iOS puzzle game I played sometime around 2017-2020. It was a Rube Goldberg-style ball runner shown from a fixed isometric / 3D-illustrated perspective, played in landscape orientation only. Each level had multiple balls (I think around 5) that would roll from the left side of the screen to the right after you triggered the start, and your job was to guide them all to the goal.

The core mechanic was a pair of on-screen buttons — one red, one blue — that activated matching-colored mechanisms within the level (latches, fans, gates, that kind of thing). It was a mix of timing and logic, where you had to hit the right trigger at the right moment to keep the balls moving along the path.

Aesthetically it was very minimalist and refined — almost the entire level palette was white and gray, with the marbles themselves being dark gray or black. The only other colors that appeared were red and blue, and those only showed up on the interactive elements you controlled. The whole thing had a Bauhaus / Swiss design / Monument Valley kind of vibe — definitely premium, not free-with-ads territory.

I'm pretty sure the name was something short and elegant, possibly just a single word.

Anyone recognize this?
