This was fun! I definitely got into it for a bit. I really like the background and the bright colors you used, and the music fit the game well. What would have also been pretty cool given the main mechanic of your game, would be to have the Unicorn as two people dressed as a Unicorn (so there would be a person in the back and front) so that they would literally be connected, but it worked just fine the way you made it. Could definitely see a more polished version of this being a mobile game!
