We have just released a new version which has some slightly updated graphics for minefields and ionstorms. This is part of a larger series of changes and improvements which are currently in development and will be released soon.
The new graphics are a bit darker than the old version. If you are using the default color scheme and find that they look a little too dark to you then go into your Settings and click "Reset" to update the the latest default colors. The new colors we've chosen are a little brighter and look better with the new gradient minefields and ionstorms.
PS. The screenshot is from the massive collection of mines that Veldan
has laid down as the Robots in our game in the Indy System
which is nearing its end.
