I'm not really sure how to review this but I'll try to avoid coming across too harshly. As you pointed out, there's no objective to the map so it's basically a sandbox currently with lots of buildings you can enter and start fights in. 

I did figure out how to change your avatar and the videos showed you can interact with parts of the environment but without the objectives / game design, the large map seems like a deathmatch arena since I could do was frag the existing npcs. And I'm not sure how the map relates to the theme if it's supposed to be.  

I don't want to be entirely negative as there suburb areas are well done and resemble a neighbourhood. I do like that there are bouncepads scattered around that allow you to reach higher places or send you to the other side of the map.

However in it's current state, it's more of a proof of concept for something bigger and more fleshed out. I guess the biggest takeaway is that it's a prototype that just needs more time to cook. I wish I could say more positive things but the project is in such a early state at the moment that it's a bit directionless.

The good thing though is that will change as you develop your project further so keep at it!
