## Overview

Tidying up has never been this loud. In *Have you seen my knife? *, you're not just cleaning a workshop—you're sorting through a chaotic pile of over 1,800 parts from 216 unique guns and 17 ammo boxes, all with realistic physics. The premise is simple: someone lost their knife, and while they search, you're asked to tidy up. But what falls through the skylight isn't rain; it's a mountain of gun components that turns your cleaning task into a mechanical puzzle.

## Highlights

- **Fully Interactive Sandbox**: Once assembled, your guns aren't just for display. You can test them in the environment—grenade launchers, rockets, flares, and even a taser all work, letting you shoot at anything you see.
- **Relaxing Yet Engaging**: Despite the chaos, the game falls under Casual, Simulation, and Indie genres, offering a calming yet focused experience. It's a collectathon for gun enthusiasts and puzzle lovers alike.
