Quick answer: The biggest game UI design mistakes are clutter, not testing resolutions, small text, and ignoring confusion, fix these by keeping UI clear, testing across displays, and finding where players get confused.

UI is how players interact with your game, and common mistakes make it confusing or broken. Here are the most common game UI design mistakes and how to avoid them.

Cluttered, Overwhelming Interfaces

A common UI mistake is cluttering the interface with too much information and too many elements, overwhelming players. A cluttered UI makes the game hard to read and use, causing confusion and friction.

The fix is clear, focused UI that shows what players need without clutter. Bugnet captures where players get confused or stuck (via breadcrumbs and drop-off), so you can see if a cluttered UI is causing friction at certain points and simplify it, informed by where players actually struggle with the interface.

Not Testing Across Resolutions and Devices

A second mistake is designing UI for one resolution or device, so it breaks, overlaps, gets cut off, or becomes unusable on others. UI that looks right on your screen can break on different resolutions, aspect ratios, and devices.

The fix is designing responsive UI and testing across displays. Bugnet captures the issues and crashes that UI problems trigger across devices, so you can see UI breaking on configurations you did not test (clustering by device/resolution) and fix it, catching UI issues your screen does not show.

Using Small or Unreadable Text

A third mistake is small or low-contrast text that is hard to read, especially on mobile or from a couch, excluding players and causing frustration. Text that is readable on your monitor up close may be illegible on a phone or TV.

The fix is readable text (adequate size, contrast, and scalability) tested on real displays. Bugnet captures issues from real devices, so you can see if text/UI problems are affecting players on certain displays and address them, ensuring the UI is usable across the screens players actually use.

Avoid the big game UI design mistakes: clutter, not testing resolutions, small text, and ignoring confusion. Keep UI clear, test across displays, and find where players get confused.
