This itch.io game is one of the cleverest puzzle games I've ever played. It's also absurdly difficult.

You acquire paint and fill in squares as you hop around as a different fruit in each level, while avoiding spinning gears that will slice your poor little fruit in half. At first I thought the gears only moved when you moved, but after looking more closely, they will move slowly while you hold still, and dash forward when you press an arrow key. Each time you pick up more paint, another gear is added. It gets really difficult to keep track of everything!

Give it a try if you've got some time, it's really impressive: https://benjamin-soul.itch.io/pigments
