The principle is simple and quite intuitive.
The controls are a bit complicated and the frog's shadow misleads us. It takes a few games before you gauge the distances and get used to it.
That said, it works, there are some good ideas (single-use stones). I tried for a long time to collect the mushrooms XD.
I saw the time limit disappear on the third level.
It's very encouraging, now that the jam is over, you can polish your game and do something even more fun. Good luck for the future !
Good work !
