Burner charges
Fire a charge and the balloon rises a fixed step. That charge is gone afterward. Later in a run, fewer charges remain, so the moment you spend one matters.

Catch the bandbefore the lift is gone.
BarometerDriftAltitude puts a drifting hot air balloon in a vertical shaft. Burner charges and ballast bags each raise it by a fixed amount, and every use spends that resource for good. A target altitude band keeps moving. Reach it while you still have a lift left.

Ballast bags
A ballast bag is the other lift. It also raises the balloon by a fixed amount, and using it permanently consumes that bag. You choose the resource as well as the timing.
Four decisions in the shaft.
You do not steer a free climb. The balloon drifts, the band moves, and each lift is a single spent step. Read the gap, then spend.
-
01
Sight the band
The target is an altitude band traveling through the shaft. Its place on the next moment is part of the puzzle.
-
02
Pick a lift
Burner charges and ballast bags are separate supplies. Either one raises the balloon by a fixed amount.
-
03
Spend it once
The unit you use does not return. A lift spent early is a lift missing when the band shifts again.
-
04
Meet the altitude
Reach the target altitude while options remain. When both supplies are exhausted, the run has no further raise.
The shaft gets stricter.
As a flight goes on, careful resource management becomes the whole game. The listing describes two pressures that arrive together.
What changes
The goal stays the same: put the balloon on the moving band. The room to miss gets smaller.
- Supplies thin out Burner charges and ballast bags become more limited. Each remaining unit has to cover a real gap.
- The band wanders Target movement becomes less predictable. A raise that fit the last position can miss the next one.
