Milo Builder
Puzzles for a one-button run
Free
The run is already written. Build the level so it gets through: 144 puzzles in twelve worlds, one for each of Milo's eleven heroes and a relay of them all.
Every level in a runner is built for you to beat. Here the run is already written, and you build the level.
The hero runs right by itself, and a tape presses its one button: a jump here, a long hold there. The tape never changes. Drag pieces from the tray into the dotted zones on the level (a pad, a block, a portal, a bomb) and press Run. If the run reaches the exit, the puzzle is solved. If not, the hero dies exactly where your level let it down, the path it took stays on the board, and you move a piece and run it again.
Any solution counts. There is no par, no timer and no score: only whether the run gets through.
TWELVE WORLDS, 144 PUZZLES
Each of Milo's eleven heroes reads the button its own way, and each has a world of twelve puzzles built on that.
• Cube: a press is a jump. Build what it lands on.
• Ship: a hold is a climb. Cap it before the spikes.
• Ball: a press flips gravity. Build the ceiling it lands on.
• Spider: a press snaps across. Place the other side.
• Robot: the longer the hold, the higher the jump.
• Wave: the tape is its zigzag exactly. Clip it.
• Moth: every press is a flap, in the air or not.
• Spring: a hold only counts if a landing falls in it. Move the landings.
• Drill: a hold digs down. Shore the tunnel above buried spikes.
• Cannon: a press fires. Put the bomb where the shot will meet it.
• Ghost: held, it passes through what you built. Build under where it lets go.
• Relay: portals hand one tape from hero to hero, under water and through a mirror.
Later puzzles bring earlier heroes back through portals, and some ask the same pieces to carry two tapes at once.
EVERY PUZZLE IS PROVED SOLVABLE
Each puzzle ships with a solution that a test replays on every build of the game. Stuck? A hint places one piece of a solution, and costs nothing.
MADE OF MATH
Built on the engine of Milo Dash. Every shape is drawn by the GPU from its own outline, which is also exactly what collides: what you see is what you hit. The music is composed as it plays.
