MainFrames grabs attention with its charming art style and brilliant concept for a platformer. Exploring the world of a dying computer sounds so cool, like a digital version of The Pedestrian. Instead, MainFrames ends up as an unimpressive experience, but not one that’s outright bad either. It’s simply mediocre, and disappointingly fails to fulfil the potential of the exciting premise.

Saving your files, one screen at a time
Like platformers such as Celeste or Super Meat Boy, MainFrames’ levels consist of quick rooms with instant respawns. Your character (a sentient floppy disk named Floppy) controls easily. Floppy can move, jump and do a little mid-air spin to keep them afloat. It’s very simple, but Floopy feels great to control.
The gimmick that sets MainFrames apart is the ability to control the environment. Using a mouse cursor, the player can interact with windows on the screen and alter the stage. Using the cursor, Floppy can move platforms, activate new windows to jump on and more. Most of the game’s eight levels add a new type of window to interact with.
I really wish MainFrames did more with these environmental manipulation mechanics. It’s a cool but underutilised idea, with your control over the environment being far too limited. The mechanics frequently don’t match the computer setting, and feel like they could be placed into any platformer. MainFrames starts strong when you’re dragging platforms around like they’re real computer windows. But it’s far less interesting when you end up just turning platforms on and off for most of the game.
Despite new mechanics in every level, MainFrames’ adventure ends up feeling very samey. A lot of rooms boil down to running forward and moving the cursor to activate the next platform in front of you. It’s shocking how often you run into a room like this, especially since the game is quite short.
The other frustration is how often MainFrames slows down. Sometimes a room will require you to hit a button several times or for Floppy to run on the spot before you can continue. Since the game is built on quick restarts, you’ll need to repeat these activities every time you fail. Too much of MainFrames’ runtime is spent in sections that are frustratingly repetitive or disappointingly simple.
These mechanics also introduce moments where the controls stop feeling great. Floppy is a lot harder to control once gravity starts changing. The game requires complex upside-down platforming, and although it’s intentionally disorienting, Floppy doesn’t feel very smooth to control in this state. There are also a surprising amount of levels that the player can skip by jumping above the platforms, or dragging Floppy with the cursor. Although this seems intentional, there are far too many instances where skipping is possible.

If there is one element of MainFrames I always enjoyed, it’s the collectible daemons. Each level contains several optional rooms where you can guide a daemon through obstacles to safety. These sections contained the variety I wanted everywhere else in MainFrames. Every daemon follows Floppy differently, one might rotate around them while another bounces around like a screen saver. Figuring out how to escort each daemon is quite fun, it’s a shame the latter half of the story features far less of these optional rooms.
The other collectible is processes, short little pixel mascots which aimlessly wander around each level. Picking these up leads to cute animations and it’s fun how they cheer you on at the top of the screen, but they’re much more plain in comparison.
There’s no way to track the collectibles or to see if you’re missing any. Optional routes aren’t exactly hidden, but they’re not marked differently either, so they can be easy to miss by accidentally following the critical path. MainFrames features no way to replay levels, even after finishing the game, so it’s very easy to miss the game’s best content.

“Despite new mechanics in every level, MainFrames’ adventure ends up feeling very samey.”
MainFrames does introduce some finale setpieces in its later levels, but they’re a bit hit or miss. Level 4 features a very long platforming sequence where the player stands in one room and adjusts to a changing environment. It’s a cool concept, but it goes on for so long that making a mistake in a later section means you have to repeat the first minute of simplistic platforming every time.
Another level introduces a boss sequence where Floppy must evade a hailstorm of deadly mouse cursors raining across the level. This is quite exciting, although it did once again boil to a lot of waiting until the patterns deemed it safe to move.
Despite my frustrations, I would’ve liked more of these sequences because they were at least trying something fresh. MainFrames only took me 2.5 hours to finish, and according to the achievements, I only missed a few daemons. It’s disappointing that MainFrames feels so repetitive despite its short length. You’d expect a lot more momentum from such a quick game.

Retro look for a retro setting
MainFrames’ graphics do a fantastic job of capturing the glitchiness of a dying computer. Each level features a gorgeous pixel art vista which serves as the desktop wallpaper. Little touches such as a reflective monitor with fingerprint smudges really complete MainFrames’ look. I also love how the environment glitches out and seems to get more and more broken as you reach the game’s climax.
The foreground of each level isn’t quite as interesting. Most computer windows have the same flat look to them. It makes platforms easier to read, but I wish MainFrames got more adventurous here, as a lot more could be done with the desktop setting. There are broken spreadsheets and blue screens at one point which was nice to see, but I’m surprised MainFrames didn’t include more classic computer applications.


There are some randomly scattered windows across the game with some gorgeous little scenes. Seeing daemons operate complex machinery or taking a break at the coffee machine adds flavour to your adventure. But these rooms alongside the wallpaper backgrounds aren’t quite enough to save each level from looking rather samey.
I experienced some minor visual glitches, but nothing too disturbing. Occasionally, text would blend into the background, and the level loading screens broke after the fourth level. However, these are minor irritations. MainFrames is a very smooth ride and a small update could easily fix these issues.
Just like their controls, Floppy’s animations are simple yet terrific. Floppy’s actions are easily readable, but there’s so much peppiness included in idle animations or small interactions with the environment. The soundtrack also adds a lot of vibrancy to the game with its fun energetic chiptunes.
There is technically a story in MainFrames, but it’s more of a footnote than a driving factor. The game starts with Floppy living in their home, before being suddenly ejected and forced to navigate this new world. The adventure just sort of… goes. The game sets up a very minimalist narrative, so it’s surprising how much talking and exposition follow this barebones setup.
Between every level, you spend time talking to a penguin mascot and some other daemons that inhabit the computer. Sometimes the dialogue has a bit of charm, but it’s mostly a dry distraction to divide levels. I wasn’t sure what I was even doing for most of the game. I tried to pay attention, but the dialogue was so infrequent and unfocused. MainFrames does lead up to one interesting story moment and an eventual cute climax, but it’s all a bit sudden and unearned.
While MainFrames focuses on the sentient programs within the computer, there is a secondary story regarding the computer’s human users. This is told through environmental storytelling, except the environments are massive walls of text displayed in broken emails. I’m not sure exactly how much you’re meant to gather from these. The emails are realistically dry, but the game delivers a tell-all exposition dump in the finale anyway.
Neither pillar of MainFrames’ story really works, which wouldn’t be an issue if the game wholly focused on its gameplay and setting. But with Floppy’s inciting incident and so many opportunities to chat with the computer residents, a lot of time is spent building this messy narrative.
In the end, MainFrames leaves you with a lot of elements that don’t quite click together. But some core pillars of the game just aren’t that interesting to begin with. It’s a simple little game with some strong aesthetics. Nothing here is outright bad, there’s just not much to get out of this adventure either.
4.5
Mediocre
Positive:
- Beautiful pixelated graphics
- Smooth controls
- collectable daemons are a joy
Negative:
- Stale and uninteresting gameplay
- Lack of level variety
- Dull story
- Short runtime with no replay options
MainFrames is a delight to look at, but less enjoyable to actually play. The charming and cute aesthetics can’t save MainFrames from its simplistic gameplay which struggles to capitalise on its strong ideas.
