Thanks for testing everyone! I've collated all of the feedback I've had and there's a few (small) updates to the UI/UX that should help with onboarding and easier play.

Bugfixes:

• Happiness now no longer always open your capital
• Tech tree always shows correct data
• Fixed crash when opening a military report under specific circumstances

Cities:

• Double click a city to open it (or A on controller directly to open it)
• City screen more clearly shows which squares are being worked
• Two cities can no longer work the same square

Onboarding

• Top bar shows current research
• Onboarding tips in the bottom bar
• A discovered advance now tells you what's next

Keyboard

• Q and E are now shoulder buttons
