Top Descriptors visually dense Contains patterns where the amount of visible notes makes determining note order and/or timing difficult. , aim control Patterns with velocity or direction changes which strongly go against a player's natural movement pattern. , cutstreams Streams in which the spacing of certain notes is much larger than the rest of the stream. , collab A map with two or more associated mappers. , perfect stacks Features perfectly overlapped stacked notes using low stack leniency. , jump aim Focuses heavily on jumps, i.e. circles spaced far apart that require the player to move towards, slow down to hit, then speed up to move towards the next object. , tech Tests uncommon skills. , stamina Tests a player's ability to tap dense rhythms over long periods of time. , geometric Incorporates geometric shapes within the map's visual design. , symmetrical Employs symmetry within the map design, often mirroring elements along the horizontal centreline.
