Shrinebound

Shrinebound 0.1.0 links Minecraft: Java Edition 1.21.4 survival to your own Hollow Knight 1.5.78.11833 adventure. Gather materials and build shrines to unlock Dash and Wall Jump in your linked Hollow Knight save. Use /shrinebound journal for personal objectives. New False Knight, Hornet and Mantis Lords victories grant Minecraft materials once per world/player.

Two players share the Minecraft survival world through Melty Host/Join and e4mc, with separate personal progress. Both need their own games. Minecraft account sign-in is handled by Prism. Requires Hollow Knight's official older Steam build 1.5.78.11833; current Unity 6 is incompatible.

Early release validation: authenticated Minecraft launch, two local clients joined via the real relay, personal progress isolation, Dash shrine consumption, actual Hollow Knight dash and save reload passed. The second client used an excluded offline test fixture; two independently authenticated accounts, wall-jump gameplay, boss victory reward delivery and third-player rejection remain untested. Screenshots show actual games in a test world with supplied materials; test fixtures and saves are excluded from the download.
