I have tried various methods, but none of them can solve this problem.
1.I did not kill any animals, including scaring away crows.
2. Never eat meat, or even use any props related to animals.
3. Avoid drawing maps with snakes to prevent animals from harming them.
4.I only eat corn tortillas and drink water, but I still can't finish it by the 30th day.
5.I tried to load a lot of corn tortillas in the raft and sleep on the initial map, but still couldn't complete it on the 34th day.
6.I tried putting a lot of corn cakes on the raft and found a map without animals, but there should be a camping site on the map. When I'm hungry, I eat corn tortillas, I'm thirsty, I drink water, and when I don't get enough sleep, I go to bed. I persisted for 44 days, but still couldn't complete it.
The above are all completed in an endless mode.
Please help me achieve this achievement, thank you very much.
