It's not 100% like Minecraft, and nobody should expect that. Gameplay is significantly enriched over, say, Minetest Game, and I like MineClone 2 more than Minecraft because it provides a full experience, but is trivial to set up (download it in the browser). There's apparently a way to get a minimap with an item, but one thing I would change is the ability to just enable it or not in a menu. The cool thing is it's fairly trivial to make change like this, which I count as a plus over Minecraft.
If you like Minecraft's play style, this is a great alternative. It isn't 1:1, but it's definitely one of the best games on MineTest, with plenty of good reason.
