Yes, granted. … the game is hard to get into. But not as hard as many others where there is no beginners' info or walkthrough provided. Besides MC has -sold- more than a million copies before a proper instruction for beginners was implemented.
That being said, there is nothing more to add in terms of criticism. This is by far the best and most concise work I have seen and played so far within Minetest as a single player.
Everything is planned out and integrated neatly with the goals of the survival gameplay in mind. The game is highly complex with the simulation of environment physics such as erosion and temperature affecting the character and their surroundings. It has its very own collection of unique items and blocks as well as modifying MT's features like stack size and inventory capacity effectively. It is challenging , even frustrating at times and still allows for a learning curve that provides enough progress to make the game highly addictive.
The look and feel reminds me of the non-voxel, commercial game "Force of Nature". But gameplay is a lot better than that, IMO.
A prime example of open-source gaming and a crystal-clear recommendation for all fans of survival games. Thanks to Minetest's and Exile's developers!
