OK, first batch of post-release updates is live:
* More sci-fi fonts (Blargh!)
* Better fullscreen-window scaling / filtering (bicubic Catmull-Rom)
* Health starts full now rather than 2/3
* Consumables (rushes, body shield, etc.) slightly more common, certain health/armor items slightly less
* Closing the weapon screen now switches back to your last in-game weapon (preventing accidental missile wastage)
* Room-clear drops no longer allowed in 1-block-high tunnels
* A few room tweaks / potential soft-lock fixes
Enjoy!
