After playing the app for a couple of hours, i can give you all the details lol o.e
Creation mode
-Only has the 36 original 1.2 version blocks (Ladders,Slides,etc.)
-Creating is really difficult. Not joking.
-The controls are stiff. The jump button is in the middle of the D-Pad (Making it harder to jump and walk forward at the same time).
-You can invite players to see your maps
Doesn't have the following
-Pickax/Sword
-Creatures
-Survival mode
-Piston
-Redstones
-Customization
-Mods
-Other good stuff that Minecraft PC has
Overall: Don't buy it until new updates come out
Recommendation: Get Eden. Its easy, more customization, and you have more freedom. Its so much better
