- Player can only move to valid positions. - Bricks are pushed when this is allowed. - Bricks are sunken when they end up over water. Added settings (at runtime). Added new tile (sunken tile). Fixed bug with clearing of console. - When messages changed the new text was rendered on top of clearing the old text without clearing the buffer.
