For the most part, the game was fun and well polished! However, I will note that the turtle on its own could be quite frustrating as landing on a slope was essentially a game over without being joined together as the turtle just couldn't walk up it. Also, since your using Unity, you want to set the Rigidbody2D collision mode on certain floors from discrete to continuous as you can clip through floors with the split mechanic (I was able to do this on the first level with the arrows telling you where to go).
