First of all, Australian Mode? You made me laugh!
Now the game xD It felt like I was very strong from the start, and I couldn't really tell what the reach on my weapon was. At no point did I feel like I was in real danger, I would just run around enemies and hit them until they died. That being said, I feel like there's something here. You have a large variety of enemies, and if the controls and the presentation was a little more polished, I feel like this could bring some seriously fun gameplay.
Good job on this!
