Nothing recorded yet. See the FMOD review.

  • No web, iOS, or Android build; it is an Electron desktop app for Windows/macOS/Linux only
  • Native format is JSON; use with other formats such as Tiled TMX requires a separate importer or custom parsing
  • Engine integration depends on separate official importers/libraries per engine (Unity, Godot, MonoGame, Bevy, GameMaker, Haxe, Playdate)
  • dev-x.y.z branches on GitHub are explicitly flagged as potentially unstable and not for production
