Just a quick release which completes some more plumbing work left over from the flecs refactor, and which upgrades some of the game assets. Specifically…

• Added new font, crosshair and bullet assets.
• Implemented a stage manager and filled with placeholder content.
• Added debug controls (F1-F4 or PgUp/PgDown/Home/End) to skip through levels.

Next steps will be to fix a bunch of small things:

• Shadows and reflections.
• Mouse controls.
• Improved movement and strafing.
• Persisted game options (for flipping the y-axis).
• Fix surface collisions on Windows build.
• Your balls asplode.

After that, it’ll be work on metaballs, first for the title screen, and then for enemies.
