I had to do a double take when I saw the number of people who worked on this.
That must have been a nightmare to coordinate, the largest team I've ever been in was 4 people and that was hard enough, 12 times that is unreal. So good job on getting a finished game submitted to the jam.
Gameplay wise, the environment was fun to explore and looked really nice, but a better camera and character controller would have made for a much smoother experience.
Also, and this may conflict with your vision for the game, but I'm not sure how I feel about using a time limit in a game about exploration. It would have been nice to get a proper chance to see the entire game, and maybe have some kind of threat introduced another way. The simplest thing I can think of is to have the dog's owner(s) try to catch them, then the game essentially becomes like a 3D Pac-man which is already a proven formula which can be built off of in any direction you want.
That's not really a criticism though, just a difference in preference/opinion.
Overall, great work!
