English Country Tune is a little puzzle game in which you control a blue square, flipping it in different directions with the arrow keys (or, on an iOS device, with a swipe). In each level, there are some number of yellow balls that you must get into yellow boxes; sometimes, there is also a blue square where you must end yourself.
The level itself is 3D, so you're flipping in three dimensions; some squares are blocking. In addition, wherever you are at present, gravity is "local down" to you, and if you flip a yellow ball into space, it will fall down, relative to you; quite often, this means losing the ball as it falls out of the screen. But if you were to approach it from the other side, it would fall in the other direction, which is often the desired behavior.
