Next Steps

Planned Game Modes

None currently! Submit ideas!

Code/Design Improvements

UI/UX

• Clean up rankings screen
  • Show countries of guesses/results (maybe with flags)
• Auto-zoom guess map to country in a country-specific game
• Rotation in Frozen mode
• Improved alert of cut off in Race mode
• Improve error handling in UI
• Override google controls in streetview, make custom divs

Server

• Convert back-end to use a real db (persistence between deployments not necessary for now)
• Use alembic to manage db migrations in real persistent db
• Timestamps/hashes in info responses so checks can be faster
• Convert to a socket-based api, to allow timing to be server-side
