Silted Stacks

Carry the archive out. Send the echoes elsewhere.

Silted Stacks is a flooded-archive stealth puzzle with eight authored, deterministic turn-based chambers. Recover each document and carry it to the exit. Dry stone is silent; water steps and decoys send traveling echoes through the passages to draw sentries away.

• Eight authored chambers in the USD 3 full edition; two selected chambers in the free demo.
• Visible patrols, traveling echo fronts and exact next-turn previews.
• Decoys, undo and restart. No real-time timer.
• All included rooms are open immediately. Recover them all for an ending.
• No persistent saves: switching keeps drafts during a visit; reloading starts fresh.
• Optional synthesized tones start off and add no information to the visible map.

Controls: W/A/S/D move, . waits, P switches Move/decoy, U undoes, R restarts. On map cells, arrows move focus and Enter/Space activates. Pointer controls include adjacent cells, direction buttons, Wait and decoy placement.
