Geometry Dash v UFO Challenge is an ambitious fan project focusing on UFO and Wave gameplay, with the creator noting improved trails for both. A robot mode is also in development. This project stands out for its unique features beyond standard platforming.
A major feature is the inclusion of a functional Vault, which took hours to implement. Press V to enter the vault, then press A to type in codes. The codes are the real ones from the original game, offering an authentic experience. Excitingly, speed portals have been added and are functional, currently appearing in the Hexagon Force level.
Unique visual options are available: press B to cycle through different backgrounds and S to switch the floor design. The creator has also implemented perfect black jump rings and added cloud score saving.
Controls are standard: use the Up Arrow, click, space, or W to jump. The vault currently has no exit besides reflagging, adding to its experimental charm. For another project with unique modes, try Geometry Dash SubZero – Character Edition.
