Gave it a shot last night before I went to bed and here's what I thought about it.
I'll start with the problems I had with it, and there were only 2 things I noticed that bothered me a bit. First one was how weapon switching worked. I know it's still early in development and maybe its not the game and my PC trying to tell me it needs to be upgraded but I noticed when trying to switch weapons. The game would have a slight delay between when I press a button to switch and sometimes it would play the animation twice before I would be able to use the weapon. It tends the break the pace in the heat of the moment which can happen a lot especially during your first few games. Second one isn't as annoying but still something I felt should be mentioned and it's AI Manipulation, I think that's the best thing to call it. How is it achieved? Well if you hug a wall and peak slightly where your able to shot and have clear sight of an enemy, depending on the position of the enemy, they will just stand there and be free for the taking. Now it doesn't always happen so that's why I wasn't heavily bothered by it. Do I think these things will cause issues overtime if they aren't fix? Well yeah but I think for a prototype its not reasonable to already call the game a fail.
In fact I actually had fun with the game, took me a bit to figure out somethings worked but in due time I figured it out and was able to play comfortably.
Now with what I liked. First the RTS/TPS Survival concept. For a few years now the games I enjoyed the most were RTS and Shooters, putting the 2 together sounds like a very awesome idea and from what I played I really enjoyed it. It'll take me time to fully get used to the concept but it was very fun. Next, the building. Now as someone who wasn't a fan of Fortnite at all I found the building system in this game pretty nice. Although maybe I missed something but nothing in the game tells you if you can get extra materials to make new things to build in case your in need of more Mines or Barricades.
Last thing I want to mention is just what I would love to see be added into Blockchain Z. The only thing that currently comes to mind and I can't be the only one that's thinking of it, Online Multiplayer. I'm not sure how it would work but I think it would be cool to see how it works if it does get added into the game.
And yeah that's all I have to say about this game as it is right now. Hope this game does well, and I'll be sure to to play this game as much as I can!
