- Fixed: the ship kept flying without input. If the game window lost focus while a key was held (another window, switching tabs), its release never arrived — the game treated the key as still pressed, and the ship kept sliding in one direction. The game now releases all keys when it loses focus.
- No more exhaust dots under the ship. The old dots from the flame era were created at fixed spots behind the ship’s centre and didn’t match the ion nozzles. Sparks now only come straight out of the nozzles.
