Warm River in Baba is You
Flag is win and you float. But the flag is surrounded by skulls that also float and are defeat.
- You can move under something that floats when you don't float.
How to win the level
Remove your float so that you can move under the skulls. A problem arises though; the water is hot and Baba is melt, which means he will melt if he tries to cross the river.
The solution is to make water float just like the skulls. You can now move under the river and the skulls, capture the flag and win!
