A very simplified dungeon explorer with a Minecraft skin attached to it.
The story wasn't vert captivating and neither was the level design - with only a few main dungeons and side dungeons to explore. It seemed they had forgone more variety of levels for just increased difficulties that could be unlocked.
Character design was a bit poor and wasn't really a lot of variety in enemy design either, though maybe that's a restriction due to the amount of enemies from the main Minecraft game.
I think if you enjoy the main Minecraft game you would probably get more enjoyment from this, if not - then there are many more enjoyable dungeon crawlers out there.
