Twindell

Two pictures sit side by side and seven things are different. Twindell draws every scene from code-made parts: meadows with sheep and windmills, kitchens full of kettles and jars, market stalls under striped awnings and aquariums with fish, crabs and sunken chests.

A difference can be a colour, a missing object, a mirrored one, one that moved or one that changed size, and it can sit in either picture. The timer runs, and every wrong tap costs five seconds.

• 30 levels: generated from fixed seeds; scenes get busier and the changes subtler
• Four themes: meadow, kitchen, market and aquarium, each with its own parts and colours
• Five kinds of difference: colour, missing, mirrored, moved and resized
• Stars for time left: up to three stars per level; wrong taps and hints cost time
• Daily pair: a new picture pair every day
• Keyboard or touch: a cursor mirrored in both pictures, or tap anywhere

Code and text written with AI assistance; checked by PN Scripts with automated tests. Every shape is drawn and every sound synthesised by code; there are no AI-generated image or audio files.
