The game has gone through a lot of updates since the last review, and I do mean a lot!
The map area has more creatures/animals/robots to kill, you can now drive vehicles, the mining part of the game has been updated to include treasures, it is now running on the professional version of Unity (instead of the free one), a lot more players are playing the game now, and a heck of a lot more stuff can be crafted from materials.
If you played this game from 2013, it has been updated a lot since then, give it another go, or just give it a go as a new player.
