We first mentioned DYO a couple of years ago, when the one or two-player platformer impressed as part of the Games Made in Berlin collection. It’s a co-operative puzzler in the vein of The Lost Vikings or Trine, but with a novel mechanic allowing you to use the split-screen border itself to solve puzzles. For instance, by finagling the screen division just right, you might be able to erase a pesky barrier, or glue a hole in the floor back together. That’s exactly the kind of outside-the-box cleverness that keeps me interested in puzzle games, so I’m happy to see that an expanded version of DYO is now available on itch.io and Steam.
