Version 0.9 is distinct for its aggressive pruning of the roster. Unlike the massive, unbalanced rosters typical of M.U.G.E.N. style games, SSF2 v0.9 focused on a curated list of characters, each with movesets derived from their source material but adapted for a competitive environment.
It is crucial to distinguish Super Smash Flash 2 0.9 from the later v1.0 or the current v1.3.1. Many casual players mistakenly refer to any pre-Luigi version as "0.9," but true veterans know the differences.
