Maybe this is a me issue, but I had some problems telling the difference between me throwing my frog and other players throwing their frogs when I was overlapping with them/right on top of their boats.
This would lead to a situation where I would think that I threw my frog at a rock and I would keep going, but in reality it was a someone else throwing their frog, who just happened to be right under me (in the same spot I was).
So I would end up not throwing my frog at all, assuming their frog was mine, just totally messing up a number of runs.
I would've personally appreciated a setting or something to highlight my frog specifically so I would be able to differentiate right away if it was actually my character throwing a frog, or some other person beneath me.
