My friend lied to me

I sent him a game I'm working on, I called him a couple hours later to see how he like it. He said yeah it's great, good job. He couldn't answer when I asked what he liked about it. When I hung up I check on his data that I collected (the game pings info about what he's doing in the game and his system and location every ten seconds). I found out he didn't even open the game.
