Kittens Game, by the developer known as bloodrizer, opens with a line about being a kitten in a catnip forest and a single option to gather catnip. Gather enough and you can plant a field. Fields grow catnip on their own, catnip feeds kittens, and huts give kittens somewhere to live. From there the game grows outward in every direction, but always through text, numbers and buttons.
Its own site calls it the Dark Souls of incremental gaming, and while that is a joke, there is truth in it. Kittens Game does not hold your hand. Kittens starve if you overbuild, winters punish careless planning, and many of its systems only make sense after you have tripped over them once. For the right player, that difficulty is exactly the appeal.
Seasons that actually matter
The calendar is the first thing that sets Kittens Game apart. Catnip fields produce more in spring and much less in winter, so a colony that looks comfortable in summer can starve when the cold arrives. You learn quickly to keep a buffer in your barns and to plan population growth around the seasons rather than simply building whenever you can.
Writing this from a Canadian February, we appreciate the realism. The seasons give the early game rhythm and tension that most idle games lack, and they force decisions with real trade-offs. It is the first sign that this game cares less about click speed and more about foresight.
Jobs, science and the tech tree
Every kitten can be given a job: farmer, woodcutter, scholar, hunter, miner and later more specialized roles like priest and geologist. Each job feeds a resource, and the balance among them shapes your entire economy. Scholars generate science, which unlocks technologies, which unlock buildings and new jobs. Libraries boost science, workshops unlock crafting upgrades, and the tree keeps branching.
Crafting turns basic resources into beams, slabs and plates, which in turn become the materials for more advanced structures. It is satisfying in the way a well-run factory is satisfying, and the interface stays readable even as the lists grow long. The pull of the next technology is strong, and there is always one more thing within reach.
Trade, faith and the strange edges of the map
As the colony grows, other races arrive to trade, from griffins to zebras, each offering different goods and interested in different resources. Religion adds faith as a currency, and unicorns bring their own peculiar branch of upgrades. Later still, a space program opens, which is a sentence that should not make sense for a game about cats and somehow does.
These systems give the mid and late game a sense of discovery that offsets its slower pacing. Each new tab feels like a new genre of problem, and the writing, full of small cat puns, keeps the tone light. We gave it a solid surprise score because it kept surprising us well into week two.
Resetting for karma and paragon
Kittens Game eventually invites you to reset. Doing so with a large population earns karma, which improves your kittens’ happiness in future runs, and paragon points, which provide a permanent production boost. There are also challenges that change the rules for a run in exchange for lasting rewards, giving long-term players new goals.
The reset is more of a long-term commitment than a quick loop. Each run can last many days, so the payoff of a reset is measured in weeks. That is a fair trade for this game’s audience, but it does mean the pacing score suffers: the early game of each run is slow, and patience is required to reach the most interesting parts.
Your opening seven days in Kittens Game
- Gather catnip by hand, plant fields early, and keep a healthy stockpile before your first winter arrives.
- Build huts steadily, but never faster than your catnip production can feed the new kittens.
- Assign a scholar or two as soon as science unlocks, because research gates almost everything else.
- Build barns and a library before pushing population further, to avoid running out of storage.
- Export your save from the options menu every few days; colonies take a long time to rebuild.
What wore us down
- The early game is slow, and resets send you back to it
- Long lists of resources can overwhelm newcomers
- Many systems are explained only lightly, if at all, in the game
What kept us clicking
- Seasons make planning matter in a way most idle games never manage
- An enormous tech tree that keeps branching into new, strange systems
- The writing is dry, funny and full of feline puns
- Rewards careful players who enjoy taking notes and optimizing
The player Kittens Game was built for
Strategy fans, spreadsheet enthusiasts and anyone who enjoyed city builders but wanted something they could leave running in a tab. It suits players who like learning a complex system slowly and who do not mind a few setbacks along the way.
Where Kittens Game lands after a week
Kittens Game is the most demanding title on our shelf and, for the right person, the most rewarding. Seasons, jobs, trade and a vast tech tree combine into an economy that feels alive. The slow early game and the length of each run keep it from the top two, but no other idle game here has given us as many evenings of thoughtful tinkering.
