I'm not familiar with the engine, but I'd imagine you can do something
like this:
```
for name, kill_count in pairs(player.all_kills) do
    -- Replace print with the appropriate GUI display function
    print(name .. " - " .. kill_count)
end
```

If you wanted to display 0 for all things the player hasn't killed
yet, you'd need to get a list of every enemy in the game; possibly
from the engine (though I have no idea how you'd go about this).

Assuming you can get that list and it's in the format `["Enemy Name"]
= X` (X can be any non-nil value), you can use this to print the
player's kill counts for everything:
```
for name, _ in pairs(enemy_list) do
    print(name .. " - " .. (player.all_kills[name] or 0))
end
```

On a side note, you can default to 0 and increment the kill count on
one line by replacing this:
```
player.all_kills[self.name] = player.all_kills[self.name] or 0
player.all_kills[self.name] = player.all_kills[self.name] + 1
```

With this:
```
player.all_kills[self.name] = (player.all_kills[self.name] or 0) + 1
```

If using two lines was an intentional choice, feel free to ignore this.
