English Project Choose Adventure

You notice the top choice is quite strange compared to the other two. The mermaid path seemed far-fetched and impossible, while the bear seemed too strong to beat. You decide to choose the Witch, which most is most likely a performance act by a strange mountain villager. Nevertheless, you set out to the location in the mountains where the witch was last seen. The upfront cost of this expedition resulted from a need for high-climate clothing, but you were able to afford the travel.

After a short journey of a few weeks, you were able to reach the halfway point for the mountain. The climate is getting colder as you proceed.
Do you continue traveling up the mountain or do you retreat home?
