The "Pocket" effect mainly affects the size of the world, but of course also the technical possibilities of the hardware is owed. One device while hiking, digging and building very quickly reach the limits of the world. Even for larger building complexes, it should, however, rich in any case, so that the game just only in the limited an aspect of the freedom of movement.
So far, despite various me dug tunnels yet encountered any natural cave. But this can of course also be random. The same applies to my observation that apparently show up no new animals. This is especially annoying, since it is not to shear sheep anscheind possible but these seem to put their wool only after the demise available. However caused, including more aggressive creepers for the supply of opponents.
The crafting system works here as already repeatedly in reviews posted unlike the PC version. Whether one finds this version better or worse, but is likely to be a matter of taste, because one chooses the desired result from a list, on the one hand the "Bastell effect" is less, but to get on the other hand faster Ergebnisssen. The scope of the Recipes is significantly lower than in the PC. There are, for example, although swords, but no armor items, which can make the encounter with the mobs uncomfortable.
The motion controller works at least on a tray with some space on the screen quite well, on smaller smartphone displays like that look different.
Version Because the program is only half done in certain areas, so that some of the above points more likely to change. At the moment, it is also so that one encounters at greater depths on minerals that are degradable, but found no collecting and usable materials. So far I have found to "productive" only coal and iron minerals. Therefore, not all of the recipes contained in the crafting library are apparently available. Perhaps there is still rare minerals that you have to look just longer.
Overall, a nice alternative for the road, which also has its charm, but is just only the "paperback edition". On the following updates however, we might be curious.
