Great beautiful game! The storytelling flows very smoothly, and naturally blend the tutorial and the variations in jump heights and speeds. The way you play with the symmetry of the level but asymmetry of speed was especially well done.
The graphics were beautiful (I really liked the colour pallet), the mystical-foresty music went perfectly with it, and I really liked the effect when they are separated.
I think the range might have been a little too small, especially in the last level were the cub has to go rather far in front, and I had to try it multiple time so the parent could catch up after activating the button without going over the limit. But that's really a detail.
So very solid entry, well done!
