Machine Madness

Machine Madness is a 2D physics-based machine-building game where you place parts, connect mechanisms, and adjust your design. Every component interacts with the physics simulation, turning simple designs into unpredictable mechanical experiments.
Build, run, adjust
Drag parts onto the board, rotate them, flip them, nudge them. The machine plays out under real physics. No scripted outcomes. Failure is usually more informative than success. There are no lives, no currency and no timers counting down.

Over fifty parts, each used for something unique

Multiple categories: Balls & Weights, Structure, Mechanisms, Force & Air, Power & Wiring, Critters, and Targets. Every part carries its own description in the in-game Parts Gallery.
Campaign

Hand-built puzzles in Campaign mode.
Each one keeps a record of your fewest parts and your fastest run and the only record to beat is the one you set yourself.
Sandbox: Build your own

+ The entire catalogue, with no limits on what you place up to 400 parts in a single machine.
+ Turn a contraption into a puzzle by putting a win condition on any part: it must be touched, or it must be activated.
+ Stock a shelf of parts for whoever plays it — anything in the catalogue.
+ Name your machines, copy them, and play them back. Save your creations.

Otto and Bracket
Professor Otto Correct keeps the workshop. Bracket is his cat, and Otto is very straightforward about him.
The professor provides some settings and options to be changed such as,

+ Windowed mode, borderless or exclusive fullscreen, resolution options, V-sync and frame cap.
+ Different graphics quality tiers. The professor always focuses on optimizing the game further for low-end machines and laptops.
+ Keyboard rebinding.
+ Interface scale, screen-shake scale, and a reduce-motion switch.
