I love this game almost as much as Minecraft. But, in my opinion, there are a few thing that are setting it back. Please add:
-Significantly better creative/explore inventories (creative inventories should give you easy access to everything in the game)
-Many, many more crafting recipes
-Music heard much more frequently
-Far better controls (such as a D-pad, easily breaking blocks in creative, and easy creative flying)
-MULTIPLAYER! And a chat for multiplayer so you can talk to players!
-Many ways to customize your world before creation, and actually able to name them!
-A way to spawn mobs in creative
-Longer day/night cycle, and smoother transition (because when going from day to night and vice versa, the world temporarily goes black)
-Smooth lighting and other graphics improvements
-FOV (Field Of View) option
If you could add these I would rate five stars, but for now I will only rate four.
