(Note: This uses Cheat Engine and so might be called cheating, but as Lugaru is a single player only game (not even containing a public high score board), I hope this isn't a problem. The same modifications offered by this mod can also be done by changing the source code (as Lugaru is open-source) - at least, if you can get it to compile (I couldn't)).
Whether you're looking for challenges, training, or just a fun time, you'll find lots to experiment with in the Lugaru Variable Playground mod! With more than 11 modes, 10 "quick modes"/presets, and numerous controls and variants per mode, you'll find plenty of ways to enjoy Lugaru like never before. Including endless combat, sword fights, "lives", becoming a fire monster, giants, midgets, and special weapon variants, there is a diverse selection of options you have to modify your Lugaru playing experience!

As implied by my note, this mod requires Cheat Engine to use.
