Just played the updated version:
I'm glad to see that difficulty levels were added. The game was much easier to play this time around.
I also liked the inclusion of Explore mode.
The wavy grass is also a nice touch.
I did encounter quite a few bugs though:
After selecting a difficulty and spawning, the player is sometimes stuck so that they can't move or even shoot. Only way I could get unstuck was by pressing Escape.
One of the village buildings was hovering over the ground.
There were multiple times where the village would have 0 health (a completely red bar) but I never got a message saying I had failed and the game never ended.
Multiplayer only said "Searching" but never did anything. There was no way to exit the search other than right-clicking on the game in the Taskbar and closing it out completely.
I think the meteors should fall closer to the village or right on top of it -- it's hard to believe that the village was destroyed when all the buildings are still there and the meteors are falling hundreds of yards away.
