The Untitled Happiness Project

Wander through a surreal 3D mindscape and poke at every glowing object to piece together what happiness actually means.

You wake up in a grey little room with a flickering lamp and a locked door. Press F on the lamp. It clicks, the light warms, and a tiny thought pops into your head: 'warmth.' That's the core loop. The Untitled Happiness Project is a quiet 3D walking sim that asks you to collect those tiny thoughts by interacting with everything that looks even slightly interactive. Chairs, windows, bathtubs, old radios – each one adds a fragment to your mindmap. Tab pulls the whole thing up, and you start seeing connections: warmth, safety, a dog barking two streets over. It's less about puzzles and more about poking around until something clicks in your own head. Movement is WASD, F is your only action button, and there's no fail state. The mindmap is the real game – it slowly fills with nodes and lines, showing how your collected fragments relate. Some objects unlock memories, others just make a noise or change the lighting. I kept hitting Tab every few minutes, just to watch the web grow. P resets the whole thing, which I only used once after I thought I'd softlocked myself behind a couch (I hadn't). The game doesn't hold your hand, but it's also impossible to truly get stuck. Esc opens a minimal menu, but honestly you'll ignore it. The 3D visuals are deliberately low-poly but the sound design carries a lot of weight. A ticking clock in one room had me standing still for a full minute, just listening. It's a short experience, maybe 20-30 minutes, but the ending depends on which fragments you actually found and connected. I missed a couple on my first run and got a bittersweet note instead of the sunnier one. It's not a game for adrenaline junkies. If you like slow, thoughtful spaces that make you feel a little hollow and then slowly fill back up, this one sticks.

WASD - movement, F - interaction, Tab - show mindmap, P - reset game, Esc - menu

Spam F on everything – even objects that look like background decoration can hold fragments. Open the mindmap early and often; the connections hint at which areas you haven't fully explored. Listen carefully. Some interactions only trigger after specific sound cues play out. If you feel stuck, walk the perimeter of each room slowly – interactive spots are often tucked near corners or behind furniture. Don't reset with P unless you're absolutely sure you're stuck; it wipes your mindmap progress. Turn up your volume or use headphones. The ambient audio tells you where to look next.
