In this demo the majority of the first level is complete but still needs a bit more added, such as The Keeper. The Second level is near complete now with a maze like structure blocking your path. The levels so far are quite small so the third one is being designed as a massive underground cavern which will be ready for your testing in a few weeks.
At the moment there are no option settings so that'll be added soon for more control over the mouse settings and graphics, graphics which can only be changed at start up.
Give us some feedback and let us know what you think, we know there's a lot to be fixed, refined and added.
