Update v0.1.20260402
New Features
- Deep Risers — vertical tunnels now connect each inter-chunk gap down through the lava zone, reachable after breaking the chunk bottom with Overheat Vent
- Veilstone — a new high-value hidden ore seeded exclusively in deep risers; completely invisible and unmineable without a Prospector's Eye ping
- Branching Mk3 Ability Upgrades — Mk3 tiers now fork into mutually exclusive upgrade choices
- Shop Tree UI — new pannable node-graph view showing the full ability upgrade web
- Faction System — Corp vs Planet Engine affinity tracking with daily quotas, mission tracks, faction-specific shop items, branching endings, and a new victory panel
- Volumetric Lava Simulation — lava now fills cells with partial volume; flow priority (down → sideways → up) prevents unrealistic horizontal chaining
- Marching Squares Terrain — cave walls rendered as a smooth mesh surface instead of individual tiles
Improvements
- Underground lighting responds dynamically to the environment
- Fog of war updated with unified underground classification and fixed visual artifacts
- Dig sound loop stops immediately when digging stops (removed 1-second grace delay)
- Terrain tiles switched to square sprites for cleaner marching-squares geometry
- Crust terrain rendering unified across chunk tops and lava-facing edges
- Underground background repaired: rock backdrop clips to the actual surface line; lava backdrop clips at the lava line; gas pocket visuals use a smoothed field with stripe/haze instead of a raw tint
- World generation performance: eliminated full-grid scans during chunk building
- Lava backdrop visuals and shader tiling improved
