This looks fantastic and love the tortoise idea (I love tortoises and had a pet one in the past), only problem is I couldn't work out the first minigame for ages then when I worked it out I had run out of time to play any further. Shame as looks like you had really put a lot into the game. I'll try and revisit after the jam.
I'm a first time game jam entrant and what I've learned in this jam is that as there so many games it is better to err on the side of creating a game that is easy to grasp and play quickly as often people only have 5 or 10 minutes for each jam game.
