When I booted up last year’s tough-as-nails and long-awaited Hollow Knight: Silksong, I knew I had to focus up and lock in – this is a Metroidvania that doesn’t go easy on you. I loved it. At the same time, you don’t always want to settle down for an evening of gaming, knowing you’re going to be turned into a fine paste for hours on end. After the path of pain I willingly trudged through in Silksong, I’m thankful for a brilliant little gem called MIO: Memories in Orbit.

It’s a Metroidvania that certainly offers up its own level of challenge, but this is a simpler, friendlier, and more pensive affair, one that I’m sure anyone with a love of the genre will find charming, intriguing, and entertaining.

You play as Mio, a nimble and fleet-footed robot, who must explore The Vessel and prevent this dilapidated AI-controlled spaceship that serves as home to a community of charming robots from a complete shutdown. To do so, you have to partake in that most classic of video game quests: collect the five MacGuffins that are scattered in the far corners of the facility and bring them together to breathe life back into the system.

Best bit

Up until you enter the Vaults in the bowels of The Vessel, MIO: Memories in Orbit has been a fairly tame and breezy Metroidvania. It’s here, though, where the game ramps up the challenge and asks you to make use of all the traversal abilities you’ve acquired so far. Plus, for the lore enjoyers, elements of the story start to become clearer, and enlightening secrets are revealed.

As you explore, the familiar language of the Metroidvania is all around you, showing you how Mio’s skills and abilities will grow and improve. These are the grappling points you’ll be able to latch onto later. Here are the doors that only open with a certain attack. There’s the chasm that can only be crossed once you can glide. Anyone with a good amount of experience with the genre will find Mio comfortable and understandable at a glance.

At first, I found this made the game a bit too relaxed for my liking, and I feel that other fellow veterans of the genre may also react this way to the game’s opening hours. Sure, I was still enjoying my time winding my way through the corridors of The Vessel, bashing corrupted robots into pieces, and breezing my way past the obstacles in my way, but I was hoping things would escalate.

What helped put off some of those initial worries was the fact that The Vessel is such a fun and fascinating place to explore. From the grandiose Metropolis with its gold-plated buildings and imposing architecture, to the overgrown gardens rife with threatening foliage that reaches out to grab you with its red tendrils, there’s an impressive variety to this constructed and isolated world floating through space.

And it looks gorgeous too: the vibrant colors and graphic novel-esque hand-drawn design make the game pop. Mio herself is a funky-looking character, too, with a swish cape and flowing strands leaking out the back of her head like hair. I especially like the general robots that inhabit The Vessel with their big blocky heads, stuck-on goggle-eyes, and expressive waves to Mio as she passes.

Special shoutout should go to the music as well, which does an incredible job of setting the tone and creating an atmosphere in each biome of The Vessel. Understated and ethereal choral singing mixes with funky electronic bops and pulse-racing boss music to create a diverse soundtrack full of originality and wonder. One particular section genuinely made me just stop and enjoy the music for a moment because it was so perfectly suited to the environment.

Flow state

Eventually, you reach the mechanical bowels of The Vessel in its vaults, one of the most engaging areas to explore, where some of the toughest platforming challenges are found as you avoid lasers, spiked rollers, and fiery pits. And here’s where MIO started to come into its own and remind me of another genre great: Ori and the Blind Forest.

Here, you can combine the various moves you’ve unlocked to string together double jumps, wall climbs, glides, and other traversal abilities to explore new locations, zip through tight sections of platforming, and survive testing combat challenges. From here on, I had countless joyous moments of entering that wonderful flow state and emerging on the other side with immense satisfaction or in awe at a new location I’d discovered (or ingeniously implemented shortcut I’d unlocked).

Yet, while exploration and platforming are where the game excels, combat is where it slumps a little. It’s never bad, but it is missing a spark or idea to elevate it. I think it’s because you simply mash a combo string of three attacks and, well, that’s about it. Yes, there’s a dodge, and yes, you can use the Hairpin power to grapple towards enemies and keep combos going in midair, but it’s all just to continue that one-two-three punch again and again.

Modifiers you buy using the ‘Nacre’ currency dropped by defeating enemies give you a chance to optimise your build and personalise your setup to suit your preferred play style, but there are limits to how many you can equip. The majority only offer light tinkering at most, too, rather than anything that meaningfully expands your offensive options.

For example, you can mark enemies to receive more damage after a successful dodge, or add a heavy attack after a grapple. It helps a little. And I did find a few fights where it excels. Combat, though, is ultimately competent and serviceable, if repetitive.

It doesn’t diminish everything else I like about MIO: Memories in Orbit, though. It doesn’t always turn out this way, but developers with a reverence for the Metroidvania genre have gone out and made an excellent Metroidvania of their own – one that I encourage fans of the genre (or just great games in general) put at the top of their must-play list.

Accessibility

MIO: Memories in Orbit has a few but limited accessibility options that are mostly focused on the game’s difficulty. These come in the form of three assists. One makes bosses easier over time by reducing their health every time you die, a pacifist option stops all enemies (except bosses) from attacking you, and the final one gives you more health after you stand on the ground for a brief period of time.

Outside of that, controls can be fully remapped, which I would encourage to more easily reach various abilities during challenging boss fights and platforming sections. Also, subtitles can be toggled on or off.

PlayStation 5 Pro on a Samsung S90C OLED TV using a DualSense Wireless Controller. A handful of hours of my playtime were also spent using the PlayStation Portal, which worked very well for this style of game.

Audio was played through a Samsung HW-Q930C soundbar, and I’d suggest a good-quality soundbar or a pair of headphones to fully appreciate the game’s excellent audio.

Although I reached an ending to the game in about 14 hours, there are additional areas to explore, bosses to fight, and secrets to uncover should you wish to go for 100% completion, which the developers say can take anywhere between 25 and 40 hours.
