0.13.1-alpha.1 — First public alpha

• Initial public release for Minecraft 1.21.1 / NeoForge.
• Karma progression, 40 distorted animal types and an aerial stage-six boss.
• Mass lightning, sky-rift arms, branching ground mouths and layered vocal horror audio.
• Full bonus-health recovery on death respawn; stage-five promotion fully heals.
• A boss without nearby eligible targets relocates to a random valid nearby stage-six player, retaining health and identity. With no valid placement, it disappears and releases the singleton reservation.
• Recent dedicated GameTest run: 53 required tests passed. Earlier scripted client checks verified rendering and vocal playback. Human difficulty rating and broad compatibility are not claimed.

Back up your world: terrain changes can be permanent. This is a playable alpha; final art, sound review, balance and compatibility work remain.
