- Toolkit code
Limitations & compatibility
- A grid toolkit, not a full game, a 3D terrain system or drop-in Godot/Unity/Unreal plugin.
- Upstream package metadata is 2.2.1; the checked source commit is pinned separately. No npm-package bytes or target runtime were tested.
- Feature-complete upstream with last repository push in November 2024; review target compatibility rather than treating it as a newly released system.
- Generated layouts still need the project's walkability, collision, spawn and gameplay checks.
- No creator screenshot/animation rehosting is approved by this batch.
