Design brainstorming

• Environments and themes

  • Moddable gltf + shaders?
  • Separate sound effect themes

• Song definitions

  • Each note has an arrival time, a continuous 2D rotation, and a fixed velocity
  • Note layouts:
    • Planar: continuous 2D positions
    • Radial: direction vector
  • Preferred environment ID
  • Content-addressed audio file

• UI Overrides:

  • Song speed factor
  • Force environment
  • Force other audio
  • Scale/offset notes

• Song Distribution

  • Hand-installed to start
  • Built-in P2P? Beware Sybil attack. Centralized trackers?

• Cheat-resistant scoring

  Upload trace of movements sampled at regular intervals, with extra samples on hit. Reject traces with impossible accelerations or missing data, then compute scores entirely server-side. Require the trace to be streamed in real time, i.e. connection open for the duration of the track) with bounded time error in sample reporting.
