A few suggestions:
1. The music. I downloaded the app the other day and the music hurt my ears. It sounded like a song you would hear in the background at the end of a YouTube video or rave music or something. It's obnoxiously loud and I automatically mute when I hear it.
2. The map. The map is, as it is now, just bad. Sooo many styles clash. The candy canes do not at all match the tileset, neither do the Christmas trees or presents. Map layout is not great either. If you want to get somewhere, you basically follow one path to get there. The thing that makes exploration games fun is trying to find different ways to get somewhere. On zone, there's a specific path that takes you where you want go and basically does not encourage much exploration.
3. Delete anything that has nothing to do with a futuristic theme. Why are there oak trees in space? Why is there fishing? Why is there a casino?
