This is soooo cute. ^_^ I think I might have bugged my starfish out one time though... it landed on a rock while the crab was in a hole, but they were both fine and I was able to move again to just put them together. I couldn't get the starfish on any other rocks through the game as far as I got. That was the level in which the starfish was introduced I believe.
But yeah this could provide a great deal of long term entertainment ^_^ It's fun to watch and listen to and lovely to get them all reunited :D Thank you so much for making it!
