About Teeth of Glass

Step inside a waking nightmare and confront the unknown in Teeth of Glass, a chilling indie horror point & click adventure that challenges your wit and resolve at every turn. You are Dr. Joshua Hagstrom, a physician whose reality collapses after "one cut" opens the door to a grotesque fever dream. Trapped and disoriented, Hagstrom must piece together twisted clues to escape a surreal, shifting world haunted by a mysterious patient and his own memories. Will you find a way out—or become lost in the madness forever?

Teeth of Glass immerses you from the first moment with its stark, moody visuals crafted in evocative low-fi HTML5 style. Shadows dance across crumbling hospital corridors, while strange, fractured scenes flicker in and out of existence. Each click draws you deeper into a layered narrative woven with psychological horror, cryptic symbolism, and emotional urgency. The game's hard difficulty will push even seasoned players, demanding sharp observation, lateral thinking, and nerves of steel.

The tension is relentless: every object could be a clue, every moment of hesitation a threat. Exploration is rewarded with narrative fragments and eerie secrets, while clever puzzles tease out the game's dual endings—will you survive to reunite with your family, or will the sorrowful echoes of the patient's past swallow you whole?

Designed by passionate indie devs for horror aficionados, Teeth of Glass stands out with its immersive sound design, atmospheric artwork, and two branching endings that beg for replay. Recent updates ensure smoother gameplay and new content for even greater replay value. While the haunting world is best experienced on desktop, this free browser adventure guarantees a pulse-pounding experience without the hassle of downloads or installs. Embrace the unknown: every decision carves a path through madness. Are you ready to test your courage where reality shatters like glass?

How to Play

Begin your harrowing journey as Dr. Joshua Hagstrom the moment you launch Teeth of Glass in your browser. The game unfolds in classic point & click fashion: hover your cursor over interactive elements in each room—doors, medical instruments, suspicious notes—then click to investigate or collect.

Your primary objective is to find clues and use them to progress through increasingly twisted environments. Examine everything carefully: subtle visuals or background sounds often hint at hidden items or puzzle solutions. Inventory management is key—collected items automatically appear at the bottom of your screen. To use an item, simply select it and click on the object or area where you think it might be applied.

Progress is driven by context-sensitive dialogue and environmental storytelling. Keep an eye out for shimmering highlights or flickering shadows; these often signify secrets or trigger story events. Teeth of Glass offers two possible endings, determined by your choices and discoveries throughout your playthrough.

Be methodical but remain cautious: the game’s hard difficulty isn’t just about tricky puzzles—it’s about survival in a place that challenges your perception. Rely on your instincts and experiment with every possible interaction. If you ever feel stuck, retrace your steps and look even closer; the solution is always lurking where you least expect it.

Beginner tip: Don’t rush. Absorb every detail, listen to the sound cues, and let each room’s atmosphere draw you deeper into the haunting narrative. Darkness and uncertainty are your constant companions—but only by embracing the unknown can you hope to escape.
