I feel I should put my 2 cents in here.
I have been enjoying this game enormously, you have no idea. My only 2 complaints are how slow you move (even when holding Shift), and that when you break open a supply crate everything has the potential to go flying everywhere (even under the ground in rare cases). Yay physics lol.
For the latter (second), I find that 3 ingots is all you can request (I usually order my ingots separately for this reason) before they go flying too far. I usually order 5, and they're still within reasonable distance.
For the former (first), I have edited the save file. Where do you find the variables? In hex code with your favorite HexEditor.
At level 7, when I decided to change this, I didn't know how easy it would be, but I knew the variable had to be in that save file somewhere. I've had mixed success with CheatEngine on games, and there's so much alt+tabbing that it's painful. So I decided to check how easy it was with the save file.
I shall not reveal all the secrets or post a how-to (due to both the above mentioned reason, leaving something to the imagination; and to having people learn about how to really USE computers :), but if you are looking to change something, it's rather easy to do in Hex code. It's even got some regular ol' English mixed in to help you on your way!
