Good game for two days and novice in Unity. 

Nice game, short and sweet. I would make the player be moved with the platform, so you don't fall off as much.

I love your ideas and I love how this was a family project too! I hoped you learned a lot, it's a cute game!

Those crab platforms... every time the character slid off one of them my soul died a little.  Fun concept but... those crab platforms, man.
