The highlights of Etherborn are undoubtedly its inventive puzzles and its constellation of small, compelling worlds. But with just five chapters, its brief runtime feels lacking, and it left me wanting for more puzzles to solve. Etherborn attempts to compensate for this by unlocking a new game plus mode after you’ve completed the game, which lets you dive into the same worlds once more. This mode is largely similar to the original one, the only difference being the crystalline orbs, which are located in harder-to-reach places. Apart from the slightly more challenging platforming puzzles, however, the electrifying thrill of discovery has largely subsided–you’ve already found all the secrets, after all–and there’s little incentive to revisit it. By the end, even the allure of these small worlds isn’t enough to make you return, with only the yearning for more remaining in its wake.
