Java.. no Java.
Cheat Engine works ok for level up your toons. Focus on 1 toon for a profession level you want him/her to work as top priority (that he/she must be doing) and search that number under standard 4 bytes (default) let him/her work again, when change search again until you got it.
It's better you get that profession low enough, so number will change very soon and speed up your search. When level is somehow high then it change too slow just to get +1 level up.
I put only 99, IDK what would be top level, but that freaking fast enough.
With that you got more than enough to don't spoil the game and get bored.
However, you can try this (copied from Steam) for items or toons (good one or bad one):
"Well, what you COULD do is enable debug mode. And that allows you, through right clicking anywhere, and hitting debug menu, to spawn pretty much, ALMOST, anything you want, in just about any quantity. Just remember it spawns on the square you rightclicked on (RB->Debug).
Here's the trick.
Documents > My Games > Gnomoria, and open up settings.ini. (Do make a backup of it first)
In the [Gameplay] section, most likely in the bottom of it, there's the "Debug = False". You simply flip it over to "Debug = True" and presto. Spawn whatever you like.
(Really, just make a backup of even the saves while you're at it.)
Sure helps to get rid of any pesky hunger or thirst. Also lets you get some premium tools or armor should you want that as well."
