New extra-dark look

Version 2.9.0 includes a new lighting option for playing in complete darkness and a small refinement to the red filter. The changes in detail:

• A new “extra dark” look has been added to the lighting settings for when dark mode is active on the device. This form of look has been designed for play in complete darkness.
• When the new extra-dark look is selected, it is also possible to choose the fill effect that is used for painting the blocks of a puzzle. This can help to keep glare to a minimum and make it easier to recognise the blocks in the low-lighting conditions.
• Small adjustments have been made to the other forms of appearance too. In particular, the dark look has darker blocks and certain elements are less bright.
• The red filter level can be adjusted in much finer steps.
