Addicting!
This is not your run of the mill shooter! the food feature adds a nice touch to the realism of the game, and planning a search pattern for the late game adds another dimension to gameplay.
To new players I'd advise you to max out digging and speed from the get go, and to get the the barb wire on the first day, then immediately save up until around the third day for the AOE damage Missle Launcher (2nd most expensive) for a blast of an experience!
