Nalleland is a homebrew platformer for the NES about a small walking bear named Nalle. She decides to go out for an adventure but finds that the land around her is filled with monsters and hazards. Luckily, she has a special pin at her disposal that can allow her to defeat those monsters and safely traverse these hazards.
In this run, Cephla does some nifty clipping glitches and a series of precise pin jumps in order to skip the end boss and collect the gem that triggers the game end sequence.
