Gapcraft, a tiny workshop for playable platform puzzles

Field notes

Gapcraft uses a 24 × 14 cell grid to assemble routes from plates, spikes, washers, a start, and an exit. Its checker searches the same integer physics used during play and can return a replay, while the LH1 level code keeps a design in a text string capped at 8 KiB. The page says local building and sharing work without an account; a separate creator-publishing layer remains unavailable and is described as dependent on a contract, wallet integration, and confirmed fees.
