Hello, I have two issues which may apply to other Mac users:
1. I cannot create a row of blocks using hold left button then right-click. As soon as I try to right click the row reverts to a single block (tedious when creating a large build). Control-click throws me down through the world.
2. F6 Placement won't allow me to select building materials. I always get the first (stone?) block, no matter which combination of keys I use. However, the vegetation selector in the Placement option works well, but is a different format from the block selector.
Initially, the + - (plus/minus) keys wouldn't work, but I resolved that by swapping them for . , (period/comma). I am using Mac Powerbook Pro OS X 10.9.5 Mavericks, with its standard keyboard.
Any advice would be welcome, I like this 'game' so much! It's great that the developer has recognised a gap in the gaming-world! In 'Rising World' the real challenge relies on the creativity of the user - the creativity of the developer is beyond words ...
