Physics stacking
Stackfall
A crane swings your next block. One tap decides how high you get.

Stackfall is a physics stacker with exactly one input. A crane sweeps each block across the tower on a fixed arc you cannot nudge, aim or undo, so you choose only the moment you let go. Stack as high as you dare, then watch what the blocks you rushed at the bottom do to everything above them.
How Stackfall plays
One input, no take-backs
The arc is fixed and the crane never stops. That single choice of timing is all that stands between the tower and gravity, which makes every release its own small commitment.
The game never speeds up
No speed-ups, no dirty tricks, no rigged physics. Towers simply get taller, and the blocks you placed carelessly early start to matter more with every floor you add.
Every block is somebody
Each piece is a small character with a face and a temperament. They squint and sweat as the tower sways, and whichever one finally falls gets spiral eyes for its trouble.
Height you get to keep
Cross a checkpoint and the base of your tower petrifies into stone, so future runs begin at that altitude. Unlocks grant capability — wider decks, leaning blocks, a preview of what is coming — rather than costumes.
