Next Steps

• Improve error handling in UI
• Override google controls in streetview, make custom divs
• Modify scoring to linear interp in the middle
• Alternative game mode: Single timer across all rounds
• Timestamps/hashes in info responses so checks can be faster
• Update React Transition Group after they are compatible with Strict Mode
