Hey, first things first, you need to make it way way easier to leave feedback! If you expect people to create a new account just with your site just to leave a bit of quick feedback, you may as well be asking them to get a coke from the moon for you - it's just not going to happen! :) Also I would've set this page to just be a comments only page - no need for it to be a full fledged forum, again, just more steps in the way of leaving feedback.
Well, I had fun, and a few funny surprises. I like the way it's going so far, even though I didn't play for very long. I see you're going for more of a Day Z type feel, with post apocolyptic deserted houses etc. Before I realised that, it was really strange experince, to go from being stranded in the middle of nowhere, walking over the landscape - and then stumbling into a random army base, with jets ready to go!
I was hesitant about the sentry turrent, and dared to walk around it - my heart jumped when it suddenly turned to face me! I was too close though. I wanted it to face some other way (so I could walk in that direction), so I got its attention, this time it got off a few shots, but it missed. I got some wood from the hangar. Jets didn't seem to do anything.
I stumbled on an abandoned house and got a medkit and soda can - things seemed to be looking up! Then I tried to crouch through a hole in the wall and instantly died! Seems like you have collision issues.
Also pressing ESC to bring up the menu didn't pause the game, and I really think it should. I came back to the game later and the sun had set.
I liked how it looks like the Australian outback when you're in the more deserty areas :)
