Really cool game. I'd probably buy something like this if it were fleshed out and multiplayer to dig on the beach with friends.
A couple pain points:
* As others said, the lag. I'm sure that's something that can be fixed.
* I had to order items with a bag otherwise they'd bounce off into the ocean. It would be nice if they had reduced bounciness when getting air dropped.
* (Not really pain) You are allowed to take the items from the tutorial into the rest of the game which lets you skip most/all the progression
I liked the skeleton model. Very nice. Nearly gave me a heart attack when I took it back on the boat and it arrived standing up right next to me!
