I'm a big fan of minecraft, so I'm willing to try out many of these block built games.
This one is good in term of graphics, very similar the minecraft, so making me feeling familiar and relaxed.
However the control is awful, especially for a shooting game as it is. It's so hard to correctly shoot down any enemies you wanted to, the bullets are basically flying like headless. This is not because I have poor shooting skills as I play many shooting games too.
Overall, it's an OK and relaxing game, but not addictive.
