A linear, decent 3D collect-a-thon platformer that plays like the studio's first foray into 3D games which makes sense since they'd been genre diving through 2D games with the Steamworld series but it's not polished or meaty enough to be anything more than unremarkable. It tells a fairly bog-standard environmentalism story and has its usual hero's journey tropes. The core Gunk-sucking mechanic doesn't get much use and doesn't factor in more than just cleaning up the general environment. But in the end, it's inoffensive and enjoyable enough and is quite short so doesn't overstay its welcome
