LOOPY!

Instruction:

Drag through three orbs to draw a loop, release to close it
Tap an orb to turn its hands
Undo / Restart / Hint buttons on the bottom bar

Loop three. Leave the rest loopy.

Draw a loop through three orbs of one colour and they vanish. Simple, except every orb has two hands on one axis, and the moment a loop closes those hands reach out and flip the neighbours they point at. Awake orbs fall asleep, sleeping orbs wake up, and an orb that gets a hand in the face is knocked loopy: stars circling its head, out of play until someone wakes it.

Tap an orb to turn its hands. Turning is free and unlimited, so every level is a small planning problem: which three to loop, and which way everyone should be facing when it happens. Tiles are stacked, so clearing the top orb uncovers the one buried underneath with its own hands and its own mood.

Empty the board and you win. Run out of awake orbs and the colour drains out of the world.
