So I titled "what did you say?".
First some guy A said "How are you?"
And he set information of target. : target length, divide range, text size, etc.
Then he send message to guy B.
B received message from A.
But A cannot see the message because message is behind from target.
A should eliminate target looks like post-it using gun or arrow, etc.
If A eliminate all target, he can see the message.
Then A will send message after setting more difficult.
Point :
If they set more harder,
they can set number of bullet or more long length from target, etc.
