Development Notes: Building Accessible Dino
Accessible Dino started with a simple goal: take a familiar one-button runner and make it playable for more people— especially players with low vision or anyone who benefits from slower pacing and clearer feedback.
Why an “accessible” version?
The classic Chrome Dino-style runner is easy to learn, but it can be fast, visually dense, and heavily timing-based. For many players, that means obstacles appear too quickly, contrast may not be ideal on every display, and most cues are visual. Accessible Dino focuses on clarity, control, and feedback—without turning the game into something different.
- More time to react through slower pacing and improved obstacle spacing
- More ways to perceive what’s happening via audio cues and high-contrast support
- Less friction: instant play, lightweight, and self-hosted
What we changed
1) Slow Mode as the default
The game launches in a slower, more forgiving mode by default. This reduces acceleration, lowers top speed, and improves obstacle spacing so players have more time to react and learn the rhythm.
2) Audio cues for approaching obstacles
Instead of relying only on vision, the game provides sound-based hints when obstacles are close. The goal isn’t to replace gameplay, but to add an extra channel of information—especially helpful for low-vision players or anyone playing on a small screen.
3) High-contrast option
A high-contrast / inverted mode is available for better visibility depending on your display, ambient light, or personal preference.
4) Keyboard-first controls
The game remains fully playable with standard controls:
- Space / Up Arrow: jump
- Down Arrow: duck
- Enter: restart
We also keep on-page controls (Start/Pause/Restart) for players who prefer explicit buttons.
5) Lightweight, self-hosted, and fast
This build is designed as a single, self-hosted page—no downloads, no accounts, and minimal friction. It loads quickly and runs smoothly on both desktop and mobile.
Accessibility is never “done”
Accessibility isn’t a checkbox—it’s an ongoing iteration. If something feels unclear (timing, volume, contrast, button sizes, focus states), we treat that as actionable feedback.
