If you are looking to install or use this specific version (v1.2c), Quick Start Guide for Springblades v1.2c

While contents vary by developer, a .v1.2c patch usually includes:

: Most community-created content requires extraction directly into the game's root directory or a specific /Mods subfolder.

: Improved collision detection for the spring mechanism.

: Always create a backup of your existing "Mods" or "Assets" folder. Small updates like "v1.2c" often contain bug fixes but can occasionally conflict with other active plugins.
