GAME MECHANICS
Explore game mechanics
Browse possible checks, rewards and settings. What appears in your game depends on your World options.
The APWorld release is tagged 0.6.7, but its packaged client source reports v0.6.2 and its archipelago.json does not declare world_version or a minimum Archipelago version. The separate Cave Story Randomizer version is not pinned in the setup instructions. These are versioning facts from the reviewed files; compatibility was not independently established.
Browse the gameplay families that can send checks to your multiworld.
68 Distinct numeric AP location IDs in ALL_LOCATIONS, mapped to the client event table; local events and victory/death flags excluded.The release registers all 68 numeric checks by default. The default Exclude Hell Locations setting marks two Sacred Grounds checks to avoid progression or useful placements; it does not remove them from the AP location table. Counts are static source counts, not a generated seed.

Known scope and limitations
- Install the APWorld and download a separate copy of cave-story-randomizer. Open Cave Story Client in the Archipelago Launcher, select the randomizer's root folder containing pre_edited_cs, connect to the room, then launch through the client. Linux requires Tweaked. The client patches files inside that selected directory, so use a dedicated copy.
- This listing concerns Freeware/Tweaked, not a confirmed Cave Story+ Steam integration. Linux support is documented but has not been tested here. The separate randomizer release observed is 2.4.3 and has no release assets; its code, binaries and compatibility with this APWorld remain unreviewed. No runtime or security certification is claimed.
- Keep the client, game and APWorld versions paired; compatibility with other combinations is not established in the reviewed sources.
