I am currently stuck on the geisha house mission. I've checked a walkthrough on www.gamefaqs.com and it states that from the previous mission, the weapons and ammos will be used for this mission.
My problem is that I have just completed level 3, the bunny level, and i went straight to the geisha house mission, without realising the level and I found out it is level 6. I am in the geisha house mission with only my sword.
I was wondering if there is a way to get out of the geisha house mission? without redoing the game again. Or if there is a way to complete the mission without needing a gun at the beginning.

Thanks in advance
