Thank you so much for playing this game! It’s designed to be played on mobile, where the experience is much smoother. On desktop, the directional controls don’t really work well—you’d need both hands to operate it, and we haven’t fully optimized that part yet.
As for the falling detection: if even the edge of the cow’s foot touches the river, it’s counted as a fall.
The difficulty is indeed very high. The original design goal was to make players work hard to unlock each new level—you have to keep progressing to see what comes next.
Really appreciate your valuable feedback. I’ll definitely check out your game and share my thoughts as well. Thanks again—hope we can all keep making better games and get more people playing!
