Known Limitations & Roadmap

Honest accounting of what works, what’s missing, and what’s planned.

v0.1 (Current)

What works:

2D sprites, tilemaps, animation, collision, projectiles, health/damage, AI behaviors
3D voxel worlds with 43 block types, 20 biomes, procedural terrain, caves, ores
FPS controller with WASD, mouse look, jump, fly, sprint, swim
DDA raycasting for block breaking/placing
WebGPU with automatic WebGL2 fallback
Procedural shader textures (no texture files needed)
3.4MB WASM binary, 39 unit tests

What’s limited:

Fixed world size — Worlds are a flat array in memory (max ~256x64x256). No infinite/chunk-streaming worlds yet.
No block lighting — Only vertex ambient occlusion and a fixed sun direction. No torches, no dynamic lighting.
No audio — The audio subsystem is scaffolded but not wired to the game loop.
No mobile touch input — FPS controller requires keyboard + mouse.
No frustum culling — All chunks are drawn every frame regardless of camera direction.
No texture atlases — Procedural textures only. No way to load custom block textures.
No vegetation geometry — Flowers, grass, mushrooms render as full cubes, not cross-billboards.
No water flow — Water is a static block type, not a fluid simulation.
