Any possible way of 'cheating' ?

[Tottel]

Go to the maps folder and edit the .hps files of a map.

in OnEnter(), place this:

for(int i=0;i<100;i++) GiveItemFromFile("tinderbox_"+i, "tinderbox.ent");

Which will give you 100 tinderboxes when you enter the map.
I'm just saying that you CAN "cheat". But it might ruin the game experience; it's up to you.

Note: I'm not sure what will happen when you already have some tinderboxes prior to launching that map.
