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.
Basic, but perfect if you just want to break and build stuff
If you want something that is just mining and resource management with no mobs, this is a great game. People are right that it is barebones, but that's the point: To show the basics of what this engine can do.
If you want mobs, mods are easy enough to add so you can have them or you can just play another game. Minetest Game also provides enough for somebody who just wants to mine and build to do so, which is perfect in its own way.
