based on everything ive read so far in the update release notes and everything ive played in this game so far, helping out the mino-guard hasnt been implemented yet. i switched from playing the Free version here (5.3) to playing the more recent Patreon Version (6.0) but still only have the one option of letting his soul free with that poor guy. the other option still says "not implemented yet" im afraid
im not worried though, the game is very much still in production and i can only imagine the kinds of upcoming content that will be coming! <3 <3
