There is no way to grind currency if you get stuck and lose. It seems to force a real world money purchase. Also no way to move the base in an emergency or to expand your buildable area.
I your using the rating system you have there needs to be away to play vs players that have a different rating from you. Maybe a hard challenge button or easy challenge button that matches with 150pts different.
Nice idea, and i like the little explanations at the end but the game play is much to fast initially. It would be nice if healthy already had a mucus layer provided by good bacteria to start, and only inflamed or disease states had that stripped away.
Interesting game idea. After playing through for a while i realized that the game author must be english or at least european. Half the sports questions seemed to be about soccer and there seems to be a high proportion of history questions about england as opposed to anywhere else. Know that going in an you'll be fine.

You can re-roll the map with the "New" button on the campaign screen, and constructor auxiliary and expansion tech let you expand build area.
