My remake of icedcave's legendary Top 1 Geometry Dash Extreme Demon, Slaughterhouse... made in the 1.3 editor. This used to be the hardest level on the 1.3 GDPS (Geometry Dash Private Server), but the server has since shut down. However, I reuploaded it to 1.4 GDPS and the main 2.1 servers, so you can play it there.

NOTE: This is a cut run and not a full legitimate playthrough. However, this level was verified legit, which you can see here: [ Ссылка ]
1.4 GDPS: [ Ссылка ]
