Making a little web app for BHK’s birthday, so she doesn’t have to wait for ads on the app.

Features:

Password to recreate the same puzzle to share or do again sometime

Hint system (incomplete).

Dynamic puzzle creation, checks to be sure purely logic based solutions should work, give iterations until a feasible solution was found. (Still testing, I think it works)

For debugging, may stay after – auto x incompatible cells after placing a cat

Highlight cats red if placed in an illegal cell

Should work on a smartphone

Dynamic css grid to make it scale

“pop-in” animations for emojis, shaking for errors, glowing for hints, and a pulsing loading overlay.

Automatically calculates thick and dashed borders based on the generated region map.

Share button attempts to copy the exact board code to the user’s clipboard.

highlights rule violations (cats touching, two cats in a row, etc.) by making the cells shake and glow red.

Things to consider – better ux, be able to “paint” with a finger swipe

Larger or different grids, different themes instead of pastels? Could this be played on hexagons or triangles?

Sounds

Auto-play?

Better “success” bubble
