A video from the gameplay so far. Yes, there's a treasure marked by the X on the other end of the map.
Happy with the wind and steering mechanics. Realistic, a bit arcade style exaggerated, tough but playable. Takeoffs are possible if ugly, landings are... not so soft.
The terrain rendering - currently all 2D sprites - is hitting some limits on mobile, so I probably have to look into some of the accelerated libraries. Currently I'm taking shortcuts and scaling down FOV when that happens, because we want to focus on the fun parts. Refactoring is for when the kids are sleeping...
We're thinking of adding badges for achievements and sightseeing goals. That'll allow us to add lots of things to discover.
