Never having been a big fan of Limbo or Inside, Cocoon struck me as breathtaking in its creativity for world and puzzle design. Cocoon also has the Portal effect of changing the way you think throughout your playthrough, which is extremely satisfying when you look at a puzzle and intuit the solution right from the get-go!
Oftentimes mind-bending, Cocoon has satisfying audio design that accompanies every correct solution, and an OST that, while not fantastic, does a great job of setting the mood for a weird journey through a bizarre sci-fi world.
Strong recommendation for anyone who's looking for a short puzzle adventure game!
