TerranQuest beta version 1.6.2 is being released now.
The GPS code has been adjusted to hopefully work better when it cannot get a location. We've fixed some issues with the chat and text wrapping.
You can now interact directly with other players. We've added item sending, where you can give a nearby player items from your inventory.
We also added private messaging and @user tagging. If you include the @ symbol followed by another player's username, they will see a red message icon at the top of the main screen. You can send a private message directly without it appearing in chat, too. Tap on the user's name from the Nearby list, the chat box, or on a place menu to open their profile and send a message. You can open your own profile to read, mark read, and delete messages.
Enjoy the update!
