Build Up!! vs Overpressure

Build your structure as high as you can! Gather additional building nodes along the way and reach the checkpoints!

Nothing falls here. There is no gravity in the jar, so nothing settles and nothing stacks. The whole mass drifts, and everything you put in it stays within reach. Reach in with one finger and stir. The pile follows your hand: carry a number across the jar, curl the mass around, push two of the same together and watch them become the next one up. Every other drop-and-stack puzzle forbids touching the pile. Here it is half the game. The other half is the button. Hold it and it deforms under your thumb as it charges; let go and numbers burst out of its rim. A quick tap gives you exactly one. A full charge gives you a handful of five to fifteen, and where you pressed on the dome aims them - press near the edge and they fire sideways as a jet. Three beats mark the charge; release on the fourth for a PERFECT and a bonus. PRESSURE IS THE ECONOMY The jar fails on density, not height. Pressure is how much of the jar is occupied, so every drop spends space and every merge buys it back - two become one that is smaller than the pair, and the bar falls. There is no line to cross at the top, because there is no top. 100% IS NOT DEATH Going over is survivable. What ends a run is time spent over the line. A fuse fills while you are over and drains while you are under, so a spike from one big burst is fine and a jar you cannot bring back down is not. Merge your way under and the fuse empties. ONE THUMB Hold and release is the entire control scheme, and stirring uses the same finger. Nothing counts down. Ten seconds at a bus stop or an hour on the sofa - the run waits where you left it.
