Bug fix release 0.3.11 addresses:

• OSX (macOS) build
• Super-speed can sometimes (after visiting a lake tower) be engaged accidentally
• No absolute ceiling on altitude (you’re not supposed to be able to fly out of the crater)
• Relative altitude measured to lake bed, not water surface

Improvements:

• Game pauses while system menu or main map are open
• Take off and landing, and behaviour near ground, improved but still flawed
• Mouse control improved, but still possibly flawed
