Famidash is an unofficial homebrew port of the rhythm platformer Geometry Dash to the NES. It aims to "demake" the original game while still aiming to be faithful to the original gameplay. As of version 1.2, it has been split in two, one featuring 22 official levels ported from the original as well as a number of handpicked user levels, and the B-Sides, featuring 19 custom levels in total.

Walgrey collects all possible coins in the B-Sides in record time. The final coin in "Eon" is impossible to collect in this release; hence, it is not collected.

PHOTOSENSITIVITY WARNING: There are flashing lights throughout the movie, notably during the levels "SubZero", "High Life", "Super Cycles" and "Eon", which may cause epileptic seizures to those affected.

Watch this run being played back on a real console.
