Scrollback
Run. Jump. Take the high shelf.
A short momentum platformer with forgiving checkpoints and letters worth a detour.
Carry six parcels through a moonlit archive. Hold left or right to run, and hold Jump for a higher leap. Upper shelves offer letters and alternate routes; gaps and paper birds send you back to your checkpoint.
Passing a checkpoint flag saves your place, including in midair. The flag turns green and flashes CHECKPOINT SAVED. You do not need to touch it. Letters stay collected after a fall, and there is no life or time limit. Finish all six deliveries to complete the run.
