The game is ok, and has lots of potential for improvement. The game overall is fine, it's like diablo but minecraft version. The idea is simple but works.
Here are some tips for potential improvement:
1. Need more equipment slot, not just armour, at least have the same equipment piece like original MC, helmet, boots etc
2. The game doesn't pause during offline game. What is the point of not having pause function when it's offline and single player? Real world stuff happens
3. Can introduce class and skills. This will improve the replay value and add variety.
