Moon Sweepers Review: Cleaning an Entire Moon With a Toothbrush Shouldn't Work This Well

Moon Sweepers starts you off with exactly one tool: a toothbrush. Your job is to clean an entire moon. That gap between "what you have" and "what you're asked to do" is the whole joke, and somehow DragDrop Games, a two-person studio, turned it into one of the biggest surprise hits on Steam this year, pulling in tens of thousands of concurrent players within days of launch. Underneath the bit, it's a chore-sim: scoop up lunar dust, cart it to a depot, sell it, buy better tools, repeat, ideally with up to fifteen other people also waving toothbrushes around.

Pros

• The core loop is genuinely relaxing: there's no fail state, no timer, just a satisfying cycle of scooping, hauling, and selling dust that's easy to get lost in for an evening.
• Co-op is where it clicks. Lobbies of up to 16 turn a solo chore sim into a goofy group project, and reviewers consistently single out playing with friends as the best way to experience it.
• It's cheap for how much game you get and how much attention it's generating — $8.99 for a concept this viral is an easy sell.
• DragDrop has shipped three content and fix patches in the first two weeks after launch, which is a faster cadence than most games this size manage, let alone a two-person team.
• The premise is silly in a way that doesn't wear thin fast — short sessions feel purposeful even when you've only chipped away at a tiny corner of the map.

Cons

• Progression feels lopsided. Players consistently point out that new tools and upgrades unlock faster than the moon actually looks cleaner, so the power curve outruns the sense of visible progress.
• Even the bigger machines you unlock later don't clean fast enough relative to how much surface area is left, which makes the stated goal — an entire moon — feel more like a joke than something you'll ever truly finish.
• The early build had real stability problems: a freeze roughly 30 seconds after loading certain worlds, memory leaks after leaving a session, and stutter on large bases. Most of this is patched now, but it was rough at launch.
• There's no confirmed Steam Deck or Linux support — the store page lists Windows 10 only, so handheld players should go in with that expectation.
• If you want deep systems rather than a chill time-sink, there isn't a lot under the hood. This is a game about vibes and repetition, not mechanical depth.

Performance & PC

Requirements are modest: an Intel Core i5-8400 or Ryzen 5 2600, 8GB of RAM, and a GTX 1650 or RX 570 are listed as the minimum, with 2GB of storage and DirectX 11. That's a low bar, and most PCs from the last several years should clear it without issue.

What's harder to ignore is that the launch build wasn't especially stable. Players and outlets reported a freeze that hit about 30 seconds into loading some worlds, memory leaks that built up after leaving a session or demolishing structures, and garbage-collection stutter on bigger bases. The good news is DragDrop targeted exactly these issues in a follow-up patch, with reported frame rate gains on large bases and fixes for the freeze and leaks. As for handheld play, there's no official Steam Deck rating or Linux build mentioned anywhere — the store page only lists Windows 10, so treat Deck compatibility as unconfirmed rather than assumed.

What changed since launch

DragDrop has been unusually active since release. Patch 1.0.3 added save recovery for worlds that looked corrupted but weren't, moved crew upgrades onto a shared matrix so one person's purchase benefits the whole lobby, gave hosts kick/ban controls, fixed garages reselling vehicles you already owned, and reported roughly 20% better frame rates on large bases in the developer's own testing.

Patch 1.0.5 followed with a building rework — pieces can now be moved and replaced for free, deletion refunds the full cost instead of 75%, and you can build directly onto dusty ground without clearing it first. It also lifted the per-world capsule cap to 90,000, improved how the automated collector robot prioritizes nearly-full storage, and fixed the 30-second freeze, memory leaks, and garbage-collection stutter mentioned above. A new warning now appears when you make a lobby public, explaining what other players can do and how to remove them.

How it compares

Stardew Valley is the obvious comparison for low-stakes, no-fail-state chore loops, though Moon Sweepers trades Stardew's slower farming rhythm for something more physical and social. Transport Fever 3 sits in similar "watch a system you built keep humming" territory, but it's a far denser management sim where Moon Sweepers stays deliberately simple. Planet Zoo 2 shares the same cozy-management appeal and big-scale ambition, but asks for a lot more planning and long-term investment than Moon Sweepers' pick-up-and-sweep approach.

Summary

Moon Sweepers is a joke that turned into an actual good time. It won't reward you with deep systems or a sense of real completion — the moon is always going to feel bigger than your toothbrush — but as a low-pressure, genuinely funny thing to boot up with friends, it earns the attention it's gotten. The rocky launch-week performance is mostly fixed, the price is low, and the developers are clearly still working on it. If the premise makes you grin even a little, it's worth the price of admission.
