Fun but can we get more stuff?

COOL ITS ADDICTIVE but can we get a few more skins for the unicorns? I also saw on a loading screen it mentioned SEVEN worlds and thats probably a lot to make (music, design, background, effects, etc.) but the game gets kind of slow once youve done everything you can. I even bought the Lava World because I liked the music, but now I dont have any goals to reach for. :( Just some thoughts. The four stars is because on multiple devices the app crashes and I have to restart if I let my screen turn off.
