No Way Back!

No Way Back turns every step into a commitment.

The moment you leave a tile or block — any (x, z), at any height — it seals behind you with a solid, see-through red wall that runs from bedrock to sky. You can never walk, dig, or climb back onto ground you've already crossed.

How it works

• Every tile you step off is walled off, full height — the world quietly closes behind you.
• Walls are unbreakable in survival and seal the entire column, so there's no tunnelling under or climbing over your own trail.
• The sweep is exact — even sprinting and diagonal jumps leave no gaps to slip back through.
• Light on performance: no per-tile entities, no world scans, just the columns you actually walk.
• Singleplayer or multiplayer — the trail is shared, so it doubles as a co-op "don't cross anyone's path" run.
• Admin tools: /crimsontrail clear [radius] to wipe a trail, /crimsontrail toggle to switch the challenge on/off.

Compatibility

• Minecraft 26.2, Fabric (requires Fabric API). Self-contained — no other dependencies.

Modpacks are welcome — no need to ask. Please don't re-upload or redistribute the mod outside its official pages.
