Keyboard controls
Every control is a native button, link or input, so Tab moves through them and Enter or Space activates them. In a solo climb the answer field receives focus when a prompt appears; type your answer and press Enter to submit.
The Quit control asks for confirmation. Press it once and it changes to a confirmation label for a few seconds; press it again to return to the menu.
Screen readers
The answer field has an accessible label, the timer exposes the seconds remaining as a label, and the feedback panel is announced politely when a round resolves. The Endless balloon count is also exposed as text rather than only as dots.
Known limit: the clock is not announced every second, because continuous announcements would interrupt the answer field. If you rely on the timer, the visible countdown and the five-second warning style are the intended cues.
Reduced motion
The game checks the operating system's reduced-motion preference. When it is enabled, the floating climber, card and feedback animations are removed, and the scenery transition is disabled. The scenery still changes between forest and sky, but without the animated fade.
Sound
Audio starts only after an interaction, because browsers block autoplay. The sound button in the top-right of the game control panel mutes or enables effects and the ambient loop, and the choice is saved in this browser.
Display, zoom, and mobile
The layout is responsive and supports browser zoom. At narrow widths the game uses a compact control panel and a single-column answer field. The multiplayer lobby and the guides use the same breakpoints.
If text overlaps a control at a high zoom level, contact the project with the page, the mode and the viewport width so the layout can be checked.
Multiplayer accessibility
Multiplayer uses the same native controls as solo play, so keyboard and screen-reader behaviour is unchanged. The difference is the timer: the host chooses it, and the countdown is visual.
If the default timer is too short, create your own room with a longer setting rather than asking the host to change it. The host cannot adjust the timer after the climb starts.
