Undertale: Final Showdown - finally getting out of the purgatory & quests

while in the purgatory, I was forced to use weapons I haven't unlocked yet. one of them being "the empty gun", which is the only ranged weapon (only through the use of its special ability), as far as I know. Maybe I'll buy it in the future? Anyways, when everything went back to normal, I went over to Spamton and grabbed myself a quest, which I thought was gonna be hard to complete. However, I was proven wrong later on. Overall, I'm doing pretty fine, whilst getting closer to obtaining swap sans. Anyways, peace.
