Developer ustwo games just upgraded both Monument Valley: Panoramic Edition and Monument Valley 2: Panoramic Edition with full controller support which should get them bumped up to Steam Deck Verified status.
Both games are currently rated Steam Deck Playable, with the only issue on both had Valve note how they don't show the correct keybinds. Now they will, so I expect both to get re-tested and set as Steam Deck Verified.
They're incredibly highly rated, initially mobile games that eventually got an expanded PC release back in 2022. A third game, Monument Valley 3, is scheduled to get a PC release eventually with a Steam page live but no release date listed.
