Completed with 100% of achievements unlocked (1,000G). COCOON is a very impressive debut for Geometric Interactive, clearly inspired by Limbo and Inside (on which the studio's founders also worked), but now in a wholly puzzle-focused 3D setting. Taking place with a complete absence of explicit tutorial, the game nonetheless feels immediately intuitive, even with its novel core mechanic of multiple distinct worlds that the protagonist creature can dive into and out of, and carry about as spheres within other worlds to navigate through a detailed, eerie alien landscape. It's perhaps a little too straightforward at times, with many puzzles being overcome from trying to first approach that presents itself, but there are still a good number of somewhat mind-bending scenarios, especially in the latter parts of the game where juggling multiple worlds becomes commonplace. Art design is fantastic throughout, perhaps as expected given the studio founders' experience from Limbo and Inside, with a pervading otherworldliness and scenery that tells a story all by itself - and the game's ultimate ending wraps up the experience in (no spoilers) as satisfying a thematic manner as could be hoped.
