Fly the helicopter by tilting the device, swipe up/down to increase/decrease thrust. Start with the device approximately horizontal.
On each level, collect all the 'flags' in the shortest time possible. If you crash into stuff you die and have to start again.
Version 2 is a page-one rewrite. The scenery has changed completely, and is now procedurally defined, meaning (theoretically) unlimited levels. However, difficulty increases slightly for each level you progress. A level has to be completed before the next can be attempted. This means there must be some practical upper limit (though I have no idea what it is).
Requires a device with OpenGL 2 support (most modern devices). Developed and tested on a Nexus 7 and a Samsung Galaxy S5.
