Very impressed by the tremendous effort that you put in the visuals, would never have expected so much polish for a jam game. The stylized environments are gorgeous !
The UI is especially is top-notch, the menus, transition animations in levels, the fact that you went as far putting a preview images and animations for the settings, thought of making the central platform see-through in the forest level when we pass behind it, just... wow !
The gameplay concept is interesting and unique, the music is relaxing, fits the vibe very well, you did a good job on it.
The negative points so far would be that it still needs some tweaking, it's too difficult. I put it in easy and still died a lot, partly because having the same issues as Salhiaa mentioned. Also in the snow level when the route starts from the center, my fox would sometimes die in the shade. The routes can feel a bit janky at times, at one point my fox got stuck for a bit.
Anyway really excited to follow how this is going to evolve, you've got a good concept in your hands that can turn into an excellent game !
