The map feature is quite okay, but can be improved. I suggest:
- show biome according to mouse position in the down left info area: name, danger-level, sub-biomes
- the colors are hard to differentiate. Maybe provide a biome-chooser/selector which highlights the selected biomes
- show the tier of a ruin in the info area
- provide switches for the map icons (oil, lithium, vendors)
These are some good ideas and generally should be relatively easy to implement. Thanks!
