Shutter Cats

Every cat in the building wants to go home, each to its own window.

Swipe a cat and it runs until something stops it. Bricks, edges, other cats and soft cushions all stop a running cat. Only its own window, matched by colour and symbol, lets it in.

Day or Night? The building has two kinds of shutters. ☀ Sun shutters are shut by day. ☾ Moon shutters are shut at night. Flip the Day/Night switch to open a new path, but every flip costs a move, and a shutter can't close on a cat. Later on, sun cats nap after dark and moon cats sleep through the day, so you'll need to pick the right time to wake each one.

How it was made: Made by First Mover Projects with AI coding tools. The code, levels, art (drawn in code) and synth audio were produced with an AI coding assistant, then checked with automated browser tests and a solver that proves every level solvable. No third-party assets.
