Whereas the overrated Celeste is more interested in death and whining than creative expression, Octahedron can’t get no satisfaction with its basic idea of a hero creating temporary platforms to reach new heights. From level to level, developer Demimonde obsessively introduces wrinkles to his game, showcasing a thirst for change that recalls the passion of jazz trumpeter Miles Davis.
In Octahedron, the primary goal of every level is to reach the exit. You play as a blockheaded protagonist whose only power is to form platforms that disappear after a second or two. This premise somewhat recalls the 1986 classic Solomon’s Key, but Demimonde delivers a more urgent experience. To the textures and beats of a trance and house soundtrack, you can slide your temporary platforms to the left or right before they dissipate, allowing you to access the farthest corners of the game’s neon tunnels. All the while, you must keep count: initially, you can only create two platforms before needing to touch a permanent platform in order to recharge your precious ability.
The journey keeps morphing via a neverending well of rules, contraptions, and enemies. In one level, Demimonde gives you the allowance of 50 platforms that you can call into being before needing to land on solid ground, but this freedom comes with the price of having to navigate a maze of electrified walls while dodging the lasers of a stationary sentry whose counterclockwise rotations evoke a disco ball gone mad sniper. In another level, you can only create one platform at a time, unless you grab plus-sign power-ups in midair to add to your capacity.
Octahedron has no shortage of environmental puzzles that arrive with no detailed tutorial; Demimonde asks your lust for experimentation to match his. Thankfully, the ideas are as intuitive as they are stimulating, from pipes that suck you into different parts of levels to platforms that pop in and out of existence based on how far you move to the left or right. The affair becomes more complex when you gain the ability to conjure a second type of platform that shoots destructive beams from its bottom. This dominating power comes in handy when you must, say, deal with platforms that turn into bat-like pests once you get high enough above them.
Like many other platformers, Octahedron offers items to collect for a perfect performance. Unlike the case with Fez or Celeste, the collecting here feels orgasmic rather than constipated. Flowers bust out of light bulbs that you smash with your gliding platforms. Secret areas illuminate when you dare to go to precarious inches of the levels. Sometimes you pass the literal boundaries of stages. The fluidity and restlessness of Demimonde’s game is gasp-worthy.
