good, nice to play with!
For India, it would be a bit difficult to play as the roads are some times numbered and some times given a name. Dont see any hint buttun!
1. Give names of intersecting streets. 2. Reduce the circle by half (just for this street). 3. Show a photo. 4. Allow you to drop a pin and tell you the distance (but not the direction). Then you can confirm the pin or move it one more time.
