You made it playable on mobile! That's pretty nice.
Are you using 2 different colliders for the sound and collecting food? Because sometimes I head the sound play, but the food wasn't collected.
Good concept but I would give the player a way to know where he can step and where not. Otherwise it's just repeat the level over and over until you get it right and that can be frustrating.
Also I would spread the platforms a bit more apart, because in some levels you can just go through the middle to complete it. Keep it up!
Visuals are nice, but there are 2 things I would improve:
1. There should be more contrast between the map and directions the player is able to go in
2. Levels are too hard in my opinion because sometimes it isn't quite clear in which direction the fox went. Either make the path more clear or even show the hexagons for a brief moment when the fox is moving. Not sure if this would make the game too easy tho.
