Perspective-shifting puzzler Miika is on sale now for 69p / 99c, down from its usual price of £1.49 / $1.99.
It also has a new seasonal theme to celebrate the winter holidays.
Miika is a puzzle game that, similar to optical illusions of Monument Valley, relies on perspective manipulation to get around.
Change the camera angle and take advantage of the new paths that form.
The video below doesn't reveal too much of this mind-bending gameplay, but it does provide a good look at its cute 3D style.
