This game is a fantastic improvement above the original, with some great homages to it as well.
If I had some nitpicks, however, it would be the inability to drag and drop sort your truck's chest. Any chance for this UX improvement? Also, the ammo counter only goes up to 99 in the UI, but the game appears to be keeping track of additional ammo as I have seen this number not go down when using ammo for which I have collected more than 99. Perhaps this should be capped, or raise the display value above 99?
Finally, it would be great if some items which can never be used again, such as the empty gas cans, just auto-deleted from your inventory or chest, but that's an issue that a manually sortable truck chest could allow players to organize for themselves.
