Make home-page snake game playable on mobile - #5
Merged
Conversation

Add touch controls (tap to start, swipe to steer) alongside the existing keyboard input, refactor the game loop into start/move functions, fix the missing #flashing element reference that threw on start, and reposition the game screen on small viewports.
Render each row on its own line with white-space: pre so the monospace grid no longer wraps mid-row and splits tiles across two columns on mobile. Also render the initial grid on start.
Show the desktop-PC ASCII art on small screens again by wrapping the art and game overlay in a shared .scene container that is scaled down to fit the viewport, keeping the game rendered on the monitor screen instead of hiding the art.
Lower the ASCII art on small screens so its top edge no longer tucks behind the header icons, and reduce the top margin of the intro card so the text sits closer to the game instead of leaving a large gap.
Standardize the site logo, work/posts links and theme toggle to the same height and vertical position so the header row lines up, and hide the 'hello world' easter-egg text so only the play prompt is shown.

Summary
The ASCII snake game on the home page was keyboard-only (press 'g' to start, WASD to move), so it was unusable on mobile.
Changes
startGame()+move(key)so keyboard and touch share the same logic (instead of faking aKeyboardEventfor the auto-move interval).#flashingwas referenced but never existed in the markup, which threw aTypeErrorthe moment the game started..screen-contentonmax-width: 700pxso the game is actually visible on phones.touch-action: none(toggled via a.playingclass) prevents the page from scrolling/zooming during swipes.Notes
id="background"(one inindex.astro, one inIndexBackground.astro) predates this change; touch listeners bind to the first (outer) element and events bubble, so it still works.Testing
npx astro check— 0 errors.npx astro build— succeeds; touch handlers/hints present in the bundle.
