SherlockForms vs Twindow

This little game is geared towards visually impaired children. The player is tasked to find a specific shape in a set of various other shapes. Over the course of the levels the shapes get smaller and smaller. The intention is to enable a supervisor to more easily asses the child's approximate visual acuity; all the while keeping the child entertained.

Two windows onto the same warm little world. Five things are different. Twindow is a find-the-difference game built for people who want to look, not to hurry. A bakery counter at closing time. A greenhouse in soft afternoon light. A harbour street with the boats in. Two scenes, five differences, as long as you like. No clock running. There is no countdown and nothing to lose. A wrong tap only locks the pictures for a moment, so guessing never pays. Play one scene or twenty. Every difference is measured before it ships. Each difference is scored for how visible it actually is — colour distance, edge contrast, size, and how busy the surroundings are. Nothing is hidden in a single pixel, and nothing depends on telling two nearly identical colours apart. Colour-only differences must also change in brightness, so they stay findable if you are colour blind. A new scene every day. Everyone gets the same Daily Scene. Keep a streak, and share your result as a small grid that gives nothing away. Works fully offline. On a plane, on the underground, in the garden. Your stars, album and streak are kept on this phone. Stuck? After a run of misses, or a quiet spell with nothing found, the strip between the two windows offers a short video: watch it and Twindow frames the area where a difference hides (or reveals one), or tap Keep looking and carry on. Other ads appear only between scenes and on the menus, never over the pictures while you play.
