Hi agraham,
Yes, sorry, not done the docs yet - will explain movement in the docs, but its worthwhile explaining for the people who are downloading it currently as follows:
To navigate the map (and on Multiplying Lurgi / Zigzaggers screens) you must tap the screen in the area you wish to move, ... imagine you have a big X stretching across the whole screen ... click in one of the four triangles that would be there if the X was visible to navigate North, South, East etc. Its best to tap near the edge of the screen either at the top, far right, far left or bottom to ensure you dont accidentally move in the wrong direction... a few goes and you should be up to speed with the operation.
For people downloading the beta, a better visual / understanding can be seen at
Mathematical Genius Required
How does it function on the X30 / 214? All OK so far?
I'll have a bit of time tomorrow to have a dabble at Stampeding Unicorns / Stinging Arrows - I may need to look for something that can do a rapid screen chunk copy / paste.
Cheers!
