Out of Chimney

In 'Out of Chimney' you play a small smoke-cloud named 'Smokey'.
Freshly born from a fireplace within an oven, Smokey begins to float straight upwards. It tries to get out of the chimney, but soon the chimney starts to take weird turns.
Now it is on you to help the little smoke-cloud, which can only go upwards. Prevent Smokey bumping against a wall, by turning your smartphone and changing where 'up' is.
Help Smokey to get out of the chimney.

To play this game your smartphone has to have a gyroscope. In the options menu you can test, is it has one.
