A Slimekeep Steam Key — also known as a CD Key or digital code — is the official activation code you redeem on Steam and keep in your library permanently. From €6.71 (-55%) at Difmark, Steam Account format · Cheapest official key: €14.79 · 3 verified stores, 3 offers in stock · Updated 28min ago.
Slimekeep is a fast paced action roguelike with a heavy emphasis on decision making and player freedom. Adventure through procedurally generated levels, in a quest to stop the spread of corruption created by the Slime King. You'll have the choice to fight or capture slimes, visit the Slime King's lair, or hold off another day, and so much more. Think Enter the Gungeon meets Slime Rancher, with additional unique mechanics, and elements.
Unique Combat:
In Slimekeep, every slime will grow over time. You can decide between letting slimes grow for more resources, at the cost of them becoming more powerful. Or, if you'd like, kill off the slimes early, providing less resources, but making for an easier, and less risky fight. All of this with an array of over 80 unique weapons and upgrades.
Slime Pet:
If you'd like to take a more passive route to combat, you can capture slimes with a specially crafted capture gun, capable of extracting essence out of slimes, which can be used to upgrade your slime pet. Choose one, or many paths to build your slime pet around, from brute to assassin to specialty. Craft your slime pet to transform from a simple helper to a full-blown slime destroying machine.
Bosses:
Slimekeep contains a cast of 5 unique bosses. Battle against mechs, samurais, or DJs. Each boss is carefully crafted with unique art, animations, attacks, and gimmicks to create a real challenge. And to beat the game, all you have to do is defeat the dreaded slime king, in which you can visit at any time. Sounds simple, right?
GREEN (but don't worry the graphics are customizable!)
Slimekeep for PC starts at €6.71 at Difmark, 55% under the €14.79 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €14.79 at Steam.
That €6.71 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Just 3 stores stock it, 3 offers in all, so there is little here to push the price either way.
That puts it 55% under its average of €14.79 since 2025, so today is a better entry point than most days of its life.
That €14.79 key is expensive for what it usually costs.
Worked out from 214 daily records of the Steam Key for Slimekeep across 1 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
With the shared account at Difmark you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Steam costs €8.08 more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
The 1 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
All 3 offers are Global, so the code redeems on any account no matter where it was created.

What do our users think of Slimekeep for PC Digital?
A slick, pixelated roguelite with tight controls, chiptune energy, and tons of build possibilities. Players mention the “buttery smooth experience” and the weapons diversity making it a great game. In my opinion it's a super satisfying run-and-gun experience.
