Accessibility work for a real-time Canvas game requires more than adding an accessible label to the canvas. The surrounding interface, controls, status messages, motion, contrast, and error states all need separate review.
Keyboard operation
The sample can be started, paused, resumed, jumped, and pulsed with the keyboard. Focus indicators remain visible on buttons and links. Testing should include navigating to the game without a mouse, starting the run, pausing, resuming, and reaching the final summary.
Touch controls
Jump and Resonance Pulse use large buttons below the play field. They remain outside advertising areas and are spaced to reduce accidental activation. The canvas also supports split-area touch input, but the visible buttons provide a clearer alternative.
Reduced motion
When the operating system requests reduced motion, the game selects its lightest visual preset, lowers particle activity, and removes some background movement. Core obstacle movement remains because it is necessary to play, but nonessential effects are reduced.
Readable status
Score, collectibles, distance, lives, and session type are presented as text outside the canvas. A live runtime note communicates important state changes such as pause, sample completion, result checking, and confirmed completion.
Color and contrast
Important information is not communicated by color alone. Labels accompany values, buttons use text and icons, and focus outlines remain visible. Administrators can change the character and environment palette, so custom combinations should be checked for contrast before publication.
Known limitations
A continuously changing obstacle field is difficult to represent meaningfully to a screen reader in real time. The game does not claim to provide an equivalent nonvisual play mode. The surrounding guides, controls, and summaries remain accessible, and future work can include optional audio cues, remappable controls, slower practice settings, and additional contrast presets.
Testing as an ongoing process
Accessibility should be reviewed after every layout, control, color, or gameplay change. Testing should include keyboard-only use, touch devices, zoom, narrow screens, reduced motion, high contrast, and at least one screen reader for the surrounding page.
Keyboard operation
Every primary action must be available without a mouse. Test Start, Jump, Resonance Pulse, Pause, restart, navigation, and any post-sample sponsor link using Tab, Shift+Tab, Enter, Space, and the documented game keys. Focus should remain visible and should not become trapped inside the game area.
Touch targets and gestures
On small screens, controls need enough size and spacing for one-handed use. The game avoids complex multi-finger gestures and provides separate visible buttons. Testing should cover phones in portrait and landscape orientation, browser zoom, and devices with a reduced viewport caused by browser controls.
Motion and timing
Reduced-motion preferences lower nonessential movement, but real-time obstacle play still involves motion and timing. The surrounding page should not add autoplaying decorative movement that competes with the game. Sample duration and lives can be adjusted by the administrator for testing and demonstration.
Color and contrast
Hazards use shape and position as well as color. After changing the character or background palette, test the body against the nearest scenery, the face against the body, collectibles against the sky, text against every panel, and focus indicators against buttons. Color controls make branding flexible, but they also make contrast review essential.
Text and page structure
The canvas has an accessible name, while instructions, controls, and summaries are ordinary HTML. Article pages use a logical heading hierarchy, readable line length, descriptive links, publication details, and an automatically generated contents list. Form controls have visible labels and error messages should identify the field that needs attention.
Assistive technology limits
A continuously changing canvas does not provide an equivalent real-time description for a screen reader. The theme does not claim otherwise. The public instructions and final summaries remain readable, and publishers should provide a contact path for visitors who cannot use the timed game.
Repeatable test matrix
- Keyboard only at 100% and 200% zoom.
- Touch on a narrow phone and a larger tablet.
- Reduced-motion preference enabled.
- High-contrast or forced-color mode where available.
- Light and dark browser appearance settings.
- At least one screen reader for navigation, forms, and summaries.
- A slow device or Eco rendering mode.
Document findings and ownership
Each issue should record the affected page, device, input method, severity, reproduction steps, intended behavior, owner, and retest date. Documented findings make it possible to distinguish a known limitation from a regression and help the team prioritize changes that affect basic access before cosmetic improvements.
Accessibility review is not a one-time approval. It should be repeated after changing colors, controls, advertising, article templates, or the game’s timing.
