About

Tomb Architect

Read full description

You are the architect. You are also the intruder. Tomb Architect gives you a plot of desert and lets you carve whatever you like into it — corridors, halls, stairwells, tunnels, a sarcophagus, a treasury, a room that appears on no drawing. Then it does the thing no building game does: it puts you inside your own plan and asks whether you can get back out. If your tomb is easy, that is your fault. The rating says so. WHAT YOU DO • Break ground on a gridless desert plot — rooms go anywhere, and the plan links them with ancient architectural lines on its own • Raise ten kinds of chamber, from a plain corridor to an eye chamber, each rising out of the sand as you place it • Arm six mechanical traps: a falling capstone, a pressure floor that starts a chain, a rotating chamber, a sand shaft, a hidden blade, a door carved to lead nowhere • Assemble the machinery yourself in the Mechanism Engineer — lever, gear, chain, counterweight, gate — and watch it run inside a cutaway of the wall • Set four kinds of riddle and play every one of them: steer a sunbeam through mirrors, chain hieroglyphs in the order the wall demands, throw a shadow onto a carving, route water through ancient sluices • Enter the tomb. The camera drops through the sand and you walk the plan by hand, torch first • Survive Escape mode, where the tomb wakes on a clock: systems open, routes shift, doors drop, and the dunes start coming in • Listen for the hollow rooms — some chambers are only found by sound, light, or shadow • Watch the Time Shift turn your work from new to ancient to ruin to almost entirely buried • Take a verdict on seven axes — Complexity, Exploration, Puzzle Quality, Trap Design, Navigation, Secrets, Difficulty — and a rating from one to five scarabs • Replay your own descent as a glowing route line and see exactly where you gave yourself away • Recover relics into an underground museum you walk through, where every object turns, zooms, and comes apart in your hands • Take a new commission every day, carved on a stone tablet: twelve chambers only, three false paths, a route that turns on a light riddle HOW IT FEELS No tab bar, no lists, no flat menus. The main screen is one enormous tomb floating over the desert that you turn with your finger, and its parts are the way in. Screens do not appear — the interface crumbles into sand, a stone wall collapses in front of you, hieroglyphs light and join into a portal, a shadow crosses and leaves you somewhere else, or the camera simply dives underground with the sand rushing past. EVERYTHING IS YOURS AND LOCAL Every plan, relic, rating and setting is stored on your device. No account, no sign-in, no servers, no ads, no analytics, no AI. Play it on a plane. Sigils are earned by delving. Nothing costs real money, and every chamber, trap and riddle in the game is reachable by playing it.

Your past moves with you. Coin Echo is a minimalist physics puzzle about planning trajectories across time. Launch the coin, record its six-second path, and save that run as an echo. On your next attempt, the echo replays beside you—turning every useful route into part of the solution. HOW IT WORKS • Pull back to aim and launch • Watch the coin bounce across rails and walls • Save useful trajectories as echoes • Guide specific echoes through resonance nodes • Reach the goal while every required node is active WHAT MAKES IT DIFFERENT • Solve puzzles by cooperating with your previous runs • Learn from every launch instead of simply restarting • Discover ten handcrafted levels with increasingly layered timing challenges • Enjoy precise physics, focused visual design, and responsive sound and haptics • Play offline with no account required A path does not disappear when it misses. It comes back to help you.
