I see great potential in this game, but as for now it feels incomplete (that's the sad thing about game jams). I never had anything bad happen to me or the packages.
Nonetheless I really like the idea of the player being buried in package if they aren't fast enough. I would personally add ways for the player to organize themselves, like shelves or a grinder for superfluous packages. And punish the player for being in a mess of boxes, like maybe fragile packages that break or bombs that explode under the weight of other packages.
Also for some reason the "spade" packages didn't register sometimes. It did when a truck with only spades appeared but not before with trucks that had another ID beside spade. All other IDs worked fine.
