This is the best version of the game to use for almost every category, and unlike the other version under the "tools" section, isn't outdated, (at least not yet) so go ahead and play this version.

(Update on December 4th, 2025): This version is the best for violence or pacifist runs! Version 1.3 actually loses time over the final cutscene, so version 2.1.3 is best for that.
