Happy Room is a physics-based sandbox testing game where you’re given one goal: inflict as much damage as possible on test dummies using traps, explosions, and mechanical chaos. It’s a twisted experiment in creativity and cause-and-effect, where each new setup becomes an opportunity for destruction optimization and chain reactions.

Test, Observe, Modify

The dummy is placed in the center of a grid, surrounded by blank walls and floors you can equip with weapons. At first, you’ll place spikes or mines, but later you’re using lasers, gravity fields, and automatic turrets. Each tool interacts differently with others—fire spreads, explosives cause ragdoll flings, and portals send your victim looping in infinite torment.

• Equip your room with a growing inventory of traps and projectiles.
• Link traps together to form devastating combos and timed sequences.
• Unlock advanced tools like plasma guns and freezing gas through milestones.

Challenge-Based Progression

Happy Room includes missions and achievements that encourage experimentation. Can you bounce the dummy ten times using only mines? What happens if you freeze, burn, and electrocute it simultaneously? These challenges unlock new tools and reward creative planning.

• Complete trick-based objectives to expand your testing arsenal.
• Monitor real-time feedback on damage type, timing, and effectiveness.
• Replay scenarios to beat your previous destruction records.

Control Chaos and Learn from Failure

The game allows you to pause, adjust placements, and retry endlessly. You learn by watching, tweaking, and building better combinations. There’s no single right solution—just thousands of wrong ones you can enjoy on the way to perfection.

• Save and share custom layouts for maximum destruction efficiency.
• Apply environmental mods like gravity reversal or chain lightning.
• Track scoring patterns to find weak points in your design.

Happy Room is about creative chaos. It invites experimentation, rewards brutality, and never runs out of new ways to break the laws of physics—or your test subject.
