By restricting traditional movement and thrusting you into carefully constructed 2D mazes, simply getting around
Movement in Ethereal is central to its puzzles. You’re restricted to sliding across 2D planes, with carefully placed walls blocking your progress. You overcome them by hopping through the closest wall either above or below you, shifting you into an entirely new row to move across. It’s slightly confusing to wrap your head around at first, but getting the hang of seamlessly moving around each stage is satisfying to learn. Identifying patterns in level layouts lets you quickly zip around each of them, allowing you to reach your objectives with ease and comfortably map a route to your exit once you’re done.
Each stage tasks you with obtaining a series of color-coded shapes in sequential order. It’s easy to see where most are placed as soon as you enter a level, but reaching them in the order required is rarely straightforward. Although levels are small, they are labyrinthine. They are sometimes made overly complicated, with unnecessary routes and obstacles littering the peripheral of the main stage and baiting you into considering red-herring routes. Misdirection is a core principle of well-designed puzzles, but Ethereal doesn’t make it easy enough to rectify a foolish misstep. You’ll typically have to redo all your previous moves in reverse to get back on track, which is more confusing than it should be. It quickly becomes frustrating, making each error feel more like a waste of time than a constructive learning experience.
Thankfully, Ethereal’s 24 unique puzzles don’t struggle with variety. Early ones simply rely on the freshness of the game’s movement to generate complexity, but it’s not long before new interactions change how you think about moving through each level. One will rotate the level by 90-degrees, for example, turning previously insurmountable walls into new points for you to hop between. Another creates a black, negative space that offers a larger range of movement, which gives you the ability to move walls and alter a level’s layout.
These mechanisms are introduced intelligently too, by first appearing in the hub world that precede levels designed around them. Their simple introduction whets your appetite while the larger puzzles they’re used in build upon their numerous possibilities in inventive ways. At first, each stage is centered around only one of these mechanics at a time, but puzzles get increasingly challenging as Ethereal starts combining them. The difficulty curve can feel a little steep around the half-way point, and remains a little uneven up until the end, but Ethereal rarely feels unfair, only dipping into frustration when technical issues get in the way.
There were numerous instances where, after interacting with one of the aforementioned mechanisms, a bug inexplicably transported me to another end of the level–often in a position that made movement impossible. In these instances, the only solution is to restart the level entirely, which is frustrating given how long some stages can be. Having to tediously repeat numerous movements in order to return to the same spot you were before is frustrating enough, but occasionally encountering the same bug numerous times in the same level is infuriating.
Ethereal’s soothing ambient soundtrack and delightfully catchy sound effects do alleviate the frustrations to a degree, while its ever-changing aesthetic is suitably elegant and effective at keeping you engaged with its puzzles and not distracted by unnecessary visual information. The soft water colors of each stage shift with each objective you reach, eventually being diluted into a simple monochromatic theme once you’ve finished. It’s an effective way to measure your progress through a stage and help inform you of what color shape you’ve just cleared from the stage without the need for a HUD. Ethereal’s visual simplicity echoes its ease of control but doesn’t compromise its beauty in the process.
Ethereal’s 24 puzzles shouldn’t take that long to complete, only overstaying their welcome when technical issues force you to repeatedly restart them. Although there are also a few uneven spikes in difficulty, the game’s inviting visuals and soothing sound effects dress puzzles that are intelligently designed around your limited mobility. Ethereal is a satisfyingly challenging and unique puzzle game that serves as a delightful way to spend an afternoon.
