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 1.1, it has 13 official levels ported from the original and a number of handpicked user levels, all with the original music rearranged for the NES sound chip.
Walgrey improves the previous TAS by 3.36 seconds by swapping the final level with Clutterfunk, allowing the input to be ended early, as well as better optimisation.
