This is what Matrix 4 should look like :D, the atmosphere is just awesome, both visuals and music send you in this right in this dystopic world. The setting alone makes it worth it for me to play this game.
I'm not the biggest fan of destruction/build your own stuff kind of games (like besieged). But I had still a lot of fun in the few levels the demo has to offer. The destruction visuals look awesome and it's very satisfying when you end a level after trying for 15min.
Two minor things can and should be improved, in my opinion. At first, the Camera can feel clunky from time to time, especially when you build very high structures. And I would like to see some kind of tooltips for building blocks, to get a brief understanding of what they are supposed to do.
