Hello ! It's a cute little experience. I noticed you tagged it as adventure but I felt it more like a puzzle.
The mix between planned actions and real time features like avoiding bats was a bit confusing.
For me the only winning condition was to make sure to have enough steps to cross the path and not being stopped in the middle.
Eating a berry provides an additional step but it seems there were placed randomly and resulted in wasting steps in the end so there was no action to think about such as chaining berries to travel a longer distance.
The human moving faster in hard mode has no incidence on difficulty since we can't move during day anyway.
Overall, I feel like you tried to implement different gameplay elements but you did not manage to give them a common direction and create a consistence between them.
I'm curious about your thoughts during your design process :)
