For teachers and parents

Built to be playable by more people.

Accessibility here is not a settings menu bolted on at the end. Each of these changed how the game itself works, and each is written down so you can check it rather than take it on trust.

Motion, colour and contrast

Reduced motion is honoured

The game reads the operating system's prefers-reduced-motion setting. When it is on, the opening animation is skipped entirely and the continuous effects — spinning rays, pulsing glows, drifting clouds — stop rather than merely slow down.

Danger never depends on colour

Storm drops are the one thing you must avoid, so they differ by shape and motion as well as hue. Red–green colour blindness affects roughly one man in twelve, and a game that signalled danger by redness alone would be unplayable for them without ever saying so.

Contrast is measured, not eyeballed

Body text meets the WCAG AA ratio of 4.5:1 against its background, on this site and in the game. It is measured against the actual composited colour — a translucent panel over a gradient is not the colour it looks like in the stylesheet.

Peace mode, and why it keeps its own records

The accommodation that changed the most about how the game is built.

No storms, no losing

Peace mode removes the red storm drops entirely and the round cannot be lost. It exists for players who find timers and failure states genuinely stressful, and for a classroom that wants the science without the arcade pressure.

Separate records

A peace round keeps its own best score and best time, apart from the competitive ones. Mixing them would have meant a calmer mode quietly produced unbeatable numbers — so the accommodation would have cost other players something, which is the fastest way to make an accommodation resented.

Reachable mid-game

The peace sign sits at the top of the play screen, not buried in a menu, because the moment you need it is the moment the round is going badly.

Getting the beam where you want it

Three ways to aim

Drag with a finger, move a mouse, or use the left and right arrow keys. Tapping anywhere jumps the beam straight there, so a player who finds dragging hard is not shut out.

Nothing hidden behind precision

The beam is wide enough that catching a drop does not demand pixel accuracy, and charge drops are held rather than hit — a timing task rather than a reflex one.

Readable at phone size

The game is drawn at a fixed design size and scaled by a single uniform transform, so nothing is squashed on an unusual screen shape. Text keeps the proportions it was designed at.
