About LUNIUM

Step into the enigmatic world of LUNIUM, a captivating free online puzzle game that will put your wits and nerve to the test. You awaken chained in a shadowy Victorian chamber—mysterious devices line the walls, cryptic notes litter the floor, and the clock is ticking. Your unseen captor has left behind just enough clues, but it’s up to you to crack the codes, piece together the evidence, and escape before the killer returns!

Every element of LUNIUM has been crafted to draw you deeper into its immersive world. The hand-drawn, Victorian-inspired artwork brings the eerie atmosphere to life, from the intricate lock mechanisms to the flickering lamps casting ominous shadows. Explore every corner of the room—tap and drag to uncover hidden compartments, decipher strange symbols, and sift through cryptic old letters. Each clue you unearth pulls you closer to freedom, but also deeper into the story’s mystery: Who’s behind your abduction, and why?

Designed for both puzzle veterans and newcomers, LUNIUM’s smart level design ramps up the drama without ever becoming overwhelming. Intuitive controls make gameplay seamless on both desktop and mobile, letting you dive right into the challenge whether you’re at home or on the go. With no downloads or signups required, LUNIUM is instantly accessible through any modern browser, courtesy of HTML5 technology and indie creativity via itch.io.

This is more than a classic escape room—LUNIUM weaves gripping narrative threads through every puzzle. Follow the faint pencil marks, assemble the incriminating evidence, and feel your adrenaline surge with every lock that clicks open. Will your sharp mind be enough, or will the shadows claim you before the final chain falls? There’s only one way to find out: Play LUNIUM now and let the escape begin!

How to Play

Begin your journey in LUNIUM by exploring your dimly-lit prison. Use your mouse or touchscreen to interact with the environment: tap on suspicious objects, drag to inspect items, and combine clues to unlock mechanisms. Look for highlighted items—notes, keys, strange contraptions—that might provide hints or be vital to your escape.

Every lock and puzzle in LUNIUM has a clue if you search carefully. Read all documents and observe the art for hidden numbers, symbols, or patterns. Some devices require you to arrange objects or input codes found elsewhere in the room. Keep track of your inventory—items you collect can sometimes be combined or used more than once. If you feel stuck, try re-examining previously discovered elements from a new angle.

LUNIUM is designed for accessibility, allowing players to jump in with little learning curve. While the overall difficulty is easy, each step demands attention to detail. On mobile, swipe and tap naturally as you would in favorite touch-based adventure games. Remember—every second counts! Your progress auto-saves between browser sessions, so take your time and enjoy the enigmatic ride. If you solve every puzzle, you’ll not only escape but uncover the full story behind your imprisonment.
