How to Design Clear Error Messages in Games

Error messages in games—shown when something fails, like a connection error or an invalid action—should clearly tell the player what went wrong and what to do about it, in plain language, rather than cryptic codes or vague failures. Designing clear, actionable error messages is what helps players understand and resolve problems instead of being confused and frustrated.

Tell the player what went wrong and what to do

A good error message does two things: it tells the player what went wrong (clearly explaining the problem in terms they understand) and what to do about it (giving actionable guidance on resolving it). Telling what went wrong means explaining the problem clearly and in plain language—'Could not connect to the server' rather than a cryptic error code, 'You need more resources to do that' rather than a vague failure—so the player understands what the problem is. Telling what to do means providing actionable guidance—'Check your internet connection and try again,' 'Gather more resources first'—so the player knows how to resolve the problem, rather than being told something failed with no idea how to fix it. Together, a clear explanation of what went wrong (so the player understands the problem) and actionable guidance on what to do (so the player knows how to resolve it) make an error message helpful, turning a failure from a confusing dead end into an understandable, resolvable situation. Telling the player what went wrong and what to do, clearly and actionably, is the foundation of a good error message, because the purpose is to help the player understand and resolve the problem, which requires explaining the problem and the solution clearly.

Plain language, not cryptic codes or vague failures, is what makes errors helpful. The key to error messages being helpful is plain language—clear, understandable explanations rather than cryptic codes or vague failures. Cryptic codes (error numbers, technical jargon, internal error names) mean nothing to players, who can't understand or act on them, so an error message that's just a code is unhelpful and frustrating. Vague failures ('Something went wrong,' 'Error,' an action silently failing) also fail the player, who's left knowing something failed but not what or why or how to fix it. Plain language—explaining the problem and the solution in clear, everyday terms the player understands—is what makes error messages helpful, because the player can understand a plain-language explanation and act on plain-language guidance, while they can't understand a cryptic code or act on a vague failure. This means writing error messages for the player, in their language, explaining the problem and solution clearly, rather than exposing technical errors or failing vaguely. Combining telling the player what went wrong and what to do (explaining the problem and the solution) with using plain language (clear, understandable terms rather than cryptic codes or vague failures) is what makes error messages clear and actionable—helpful messages that tell the player, in plain language, what went wrong and what to do, so they understand and can resolve the problem. Designing error messages this way—clear plain-language explanations of what went wrong and actionable guidance on what to do—is what helps players handle the failures that inevitably occur, turning errors from confusing, frustrating dead ends (cryptic codes, vague failures) into understandable, resolvable situations. When something fails, a good error message helps the player understand and resolve it, which requires explaining the problem and solution clearly in plain language, not exposing cryptic codes or failing vaguely. Make your error messages clear and actionable—telling the player what went wrong and what to do, in plain language—and players can understand and resolve problems, rather than being confused and frustrated by the cryptic or vague error messages that fail to help them. Clear, actionable, plain-language error messages are what turn failures into resolvable situations for the player.

Why finishing beats perfecting

The hardest skill in indie development isn't any particular technique — it's finishing. Most games that never ship didn't fail on talent; they failed on scope, polished forever, or chased one more feature. The developers who build a real body of work are almost always the ones who got good at choosing something small enough to complete and then completing it.

That's worth keeping in mind here, because it's easy to let any one part of development expand to fill all your time. Decide what 'good enough to ship' looks like, protect that line, and treat the endless list of possible improvements as a backlog rather than a set of obligations.

Plan for the parts you can't see

Once a game leaves your machine, a lot of what happens to it becomes invisible by default. Players run it on hardware you don't own, hit problems you never reproduced, and most of them never tell you — they simply move on. The gap between 'it works for me' and 'it works for everyone' is where a surprising amount of churn quietly lives.

So plan to see what you otherwise couldn't. Watching real players, capturing the bugs and crashes they hit with the context to fix them, and paying attention to where they drop off all turn invisible problems into ones you can actually act on — which protects the reviews and retention everything else depends on.

Consistency beats intensity

Indie development is a long game, and it rewards steady, sustainable effort more than heroic bursts. A little progress made consistently — on the game, on the marketing, on the community — compounds in a way that last-minute sprints never do. The developers who finish and find an audience are usually the ones who kept showing up, not the ones who worked themselves into the ground for a week and then burned out.

Build a pace you can sustain, and protect it. Momentum is fragile and expensive to rebuild, so steady forward motion is worth more than any single intense push.

Let real players be the judge

It's remarkable how differently real players behave from how you imagine they will. The tutorial you think is obvious confuses them; the feature you agonised over goes unnoticed; the thing you almost cut becomes their favourite. None of that is visible from inside your own head, which is why watching real people play is the single highest-leverage thing most developers under-do.

Watch without intervening, resist the urge to explain, and pay attention to what players do as much as what they say. Their confusion and their choices are data, and acting on that data is what turns a game that works for you into one that works for everyone.

Polish where players actually look

Polish is not evenly valuable. Players form an impression in the first minutes and spend most of their time in the core loop, so effort spent there returns far more than effort spread thin across content few people reach. The opening, the moment-to-moment feel, and the things every player touches are where polish converts directly into how good the game feels.

Be deliberate about it. Make the first impression strong and the core interactions satisfying before widening out, because a great core with less content almost always beats a sprawling game that never feels good to play.

Good error messages tell the player what went wrong and what to do about it, in plain language—not cryptic codes or vague failures. Make errors clear and actionable, so players understand the problem and how to resolve it, turning failures into resolvable situations.
