This doesn't have the pretentious stuff of Witness.

It's a sokoban game, so it's a grid-based puzzler about moving stuff around to get to an exit. It has a bunch of characters, each with distinct mechanics. It gets really interesting when you have multiple characters in play at once, requiring you to mix their abilities.

So far, it looks to be one of the best of that genre, though it's hard to tell how it will be later in the game.
