// what it does

BUILD ANYTHING

Powered wheels that turn one way or the other, free wheels, rods, ghost rods and springs
Any connection point joins any other: carts, towers, catapults, bridges, whatever you can think of
There is never just one answer. If it gets Sunny home, it counts
A sandbox with every part and no goal: build anything, pause it, step it frame by frame

50 HAND-MADE LEVELS

The Workshop: learn the parts, then carry Sunny up ledges and over walls
The Quarry: loose crates, rolling boulders and seesaws
The Toy Shop: springs for catapults and stretchy carts
The Factory: conveyor belts, lifts and presses with timing
Moon Base: low gravity, long jumps and wide craters

FEWER PARTS, MORE STARS

Finish with the parts goal or fewer for 3 stars
Stuck? Hints go from a small nudge to the idea to part of a machine
Slow motion shows exactly where your machine went wrong

SHARE YOUR MACHINES

Every finished machine becomes a QR code, a short code or a small file
Open a friend's machine in any level and watch it run
No account and no server: the whole machine is inside the code
