If nothing else, you should play Hole and Box (opens in new tab) for its smooth jazz rendition of Greensleeves, which is chill and cheesy in the best possible way. But the game beside it is equally interesting, and pretty original for the now-established block-pushing puzzle genre.
As in Donut County, you play as a hole. But, rather than swallowing things up, you're a hole that can attract boxes towards you, because...well, I have no idea. Maybe you're using a big magnet under the earth. But as your goal here, during each stage, is to drag a cardboard box onto each patch of dirt, your holey magnetism certainly comes in handy.
It wouldn't be much of a puzzle game without some limitations, and here you're limited by the obstacles that stand between you and boxes, and by the fact that—if you're lined up with multiple boxes at once—you'll drag both simultaneously, and you might not want that. Additionally, the hole can only pull from a distance, so if a box ends up next to you, you may get stuck.
While it's kind of an odd mish-mash of an idea, it's one executed with a great amount of style, from the lovely, soft art style to—as I already mentioned—its soundtrack of mellow, smooth jazz cheese.
