Choose a group along the bottom to open its tools. Select a tool to close the picker. Click for one Slap, Bat, Hammer or Chair hit. Hold to wind up, then swing through a part or release to strike. Keep holding and draw back for another swing. Faster swings add force; a short cooldown separates hits. Holding still never repeats a hit. Use Grab to pull and throw. Side cutters snip once at the clicked point.

Hold the Laser blade and draw through a part to cut along your stroke. Cut fragments again; tiny slivers stay intact. Bazooka (Q) launches a rocket with a powerful impact blast. Place up to six unlit Dynamite charges. Click a charge with Dynamite or Match to light its two-second fuse. Nearby fire lights it and explosions trigger other charges, throwing up water when submerged. Acid melts the sprayed part; its green floor stains keep dissolving anything that lands in them. Clean room removes the stains. The washer and water hose fill barrels and leave puddles. In flooded mode, they also raise the room’s water level. Freeze the water into slippery ice and trap immersed parts; heat or a heavy hit breaks them free. Oil + match. Freeze + hammer. Pins + pulling. Water + fire. Experiment: the same material state connects every tool.

Each weapon and tool has its own button. Chainsaw, Blade launcher, Stapler, Fire extinguisher, Conductive paint, Virus, both polarity charges and each arrow type are directly available in their groups. Only Laser blade colours and Mounted saw orientation change when you select them again. Water hose is under Materials; Pressure washer and Fire extinguisher are under Tools.

Winch: click a floor, wall or support to mount the base, then click a robot part to attach its cable, up to 16 m away. Jack: click a support, then a different movable part across a gap under 2 m. Its piston pushes along that line. A cable or piston follows your aim; green means it can attach. Finish one attachment before placing the next base. Switching tools keeps an unfinished base ready for your return. An attached winch waits for a click to start. Click it again to stop reeling and hold the wire length. The jack starts after attachment; click its base to pause or resume. Wrecking ball: click a clear spot to hang a heavy ceiling pendulum above it, then drag the ball with its tool or Grab and release. Up to four winches, two jacks and two wrecking balls; Undo removes a recent placement and Clean room clears them.

Walk to points out a destination on the floor or a landing; the robot tries to reach it around furniture. Arrow keys take over while its legs can support it. Right-drag, Alt-drag or two-finger trackpad drag to orbit. Use the mouse wheel or pinch the trackpad to zoom. Middle-drag or Shift + right-drag moves the view up, down and sideways in the screen plane, without turning it. On touch, select tools and drag directly; use the view buttons below.

Sticky rockets attach to a part; click a motor to start or stop it. Rotary vise clamps the clicked part; click its base or the clamped part to start or pause the twist. Chains can hold the other end. Hold Scrap cannon to gather loose parts, then aim and release to fire. Liquid nitrogen pours onto metal and floors or fills an open barrel for rapid immersion freezing. Rust spray also fills barrels. Teleport selects an assembly, then places it at your next click, including inside an open barrel. Fastened ends stay behind with glowing breaks when the rest teleports. Rejection stamp leaves its answer in the metal.

The Dungeon’s pendant lamps swing; severing a power cable switches its lamp off. The lift, scrapyard, server and new room machinery wait for you. Load the centrifuge in The Spin Cycle, set up a crash test in Quality Control, or lift and rotate your assistant in The Showroom. Click their lit control post to start or pause. In Full tilt, click either paddle to send parts toward the bumpers. The court scores pieces that fall through a hoop.

Undo restores the world before one of the last five actions. Repair rebuilds the robot; Replace adds a fresh assistant. Both preserve room mess. Reset clears it.
