The BoxBoy series has been very quietly and consistently good over the back half of this decade. A platformed-puzzler hybrid where you make your own platforms to solve puzzles. Great spatial reasoning that does a good job of introducing new mechanics and twists across every game. At some point, they kind of all feel the same, but if you haven't played any before, this one's a perfect start. It has 2 full solo campaigns and a full multiplayer one (that can be played solo as well), which is kind of a steal at $10.

Not a perfect game or anything, but if you're either a puzzle game enthusiast or just looking for a good couch co-op game along the lines of Snipperclips, this is a great option.
