I didn't have time to put the answers when submitting the game (I had 27 seconds left O_o) So I'll do it here:
How does the game fit the theme?
You constantly have to choose whether you are going for a dog that gives less biscuit but is easier to satisfy,or a dog that gives more but is moredemanding.
Initially we wanted to add rewards for completing harder dogs, but we ran out of time.
What code and assets did you not make from scratch during the jam (if any)?
It's all homemade using Godot !
