UI Design Basics for Indie Developers

Good game UI is mostly four disciplines: hierarchy (size and contrast signal importance), spacing (generous, consistent margins on an actual grid), restraint (two fonts, few colors, one button style with defined states), and consistency (the same action looks the same everywhere). None require design talent — they require deciding rules and obeying them. That's the short version — the sections below get into the how, the why, and the mistakes worth dodging.

Hierarchy: make importance visible

Every screen has one thing that matters most — price it visually: bigger, brighter, more contrast, more space around it. Secondary actions shrink and mute; destructive actions look different from confirmations. When everything shouts (the classic indie menu of eight same-sized buttons), players read nothing and misclick everything.

The squint test works for UI too: blur your eyes at a screen and the most prominent blob should be the thing you want players to do.

Spacing and alignment are 80% of 'polished'

Misaligned edges and inconsistent gaps read as amateur before any conscious analysis. Adopt a spacing unit (8px is the convention) and snap everything to it: padding, margins, gaps between rows. Align elements to shared edges; group related things closer than unrelated things. That's most of what 'clean' means.

Touch nothing by eye — define layout in your engine's container/anchor system so spacing survives resolution changes. Hand-placed pixels break on the first ultrawide monitor.

A tiny design system, enforced

Decide once: two fonts maximum (display + body), a UI palette of a few roles (background, surface, text, accent, danger), one button component with explicit states (normal, hover, pressed, disabled), one panel treatment. Then reuse those components everywhere — settings, shops, dialogs.

Consistency is the multiplier: each individual screen built from the system looks fine, and the game as a whole starts feeling like a product. Read your text at couch distance and on Steam Deck before calling fonts done — game UI's most common shipped failure is simply text too small.

Consistency beats quality, almost every time

Players forgive simple art instantly if it's coherent. What breaks the spell is mixing: one photorealistic asset in a stylized scene, three different pixel densities in one room, fonts that belong to different games. A modest style executed consistently reads as deliberate; a patchwork of great assets reads as cheap.

Before adding any asset, ask whether it could have come from the same hand as the rest. If the answer is no, restyle it or skip it — the scene is better off without it.

Your game is judged at thumbnail size

Most people meet your art as a 231-pixel-wide capsule, a compressed GIF, or a phone-screen screenshot. Detail that only reads at full resolution is invisible at the moment of decision. Strong silhouettes, high contrast, and one clear focal point survive shrinking; intricate noise does not.

Zoom your screenshots out to thumbnail size regularly while you work. If you can still tell what's happening and where to look, the art is doing its job where it matters.

Plan for the bugs you won't see coming

Whatever else you take from this, build yourself a way to hear about problems. Once your game is on other people's machines, most failures happen out of sight: the crash on hardware you don't own, the save that corrupts once in fifty exits, the bug players mention in a review instead of a report.

A lightweight crash and bug reporting setup — even just Bugnet's free tier wired into your engine — turns that silence into a fixable list. The devs who look calm at launch aren't luckier; they just see their problems earlier.

Putting it to work

Don't try to act on all of this at once. Pick the one change that costs you the least and pays the most this week, do it, and see what actually happens before reaching for the next.

Most of this rewards steadiness over intensity. A small improvement made every week, checked against how real players respond, outruns any single burst of effort — in this corner of game development and every other one.

Coherent and modest beats gorgeous and mismatched — and check it at thumbnail size.
