It’s done! (For certain values of done.)
I could keep polishing it (and it could use more), but it’s a reasonably complete game.
Stroke the cats by clicking and dragging the mouse. When you’ve stroked them enough, they’ll be happy and give you points. But if you stroke too much, they’ll hiss and bite you! If you neglect them, they’ll leave unhappy and you’ll lose points. The game ends after one minute or three bites. Try to get the highest score!
