Hmm I figured it out too, but after 30+ tries at the same challenge... I know it's hard to get playtesters in such short time. I always post the game to my facebook 24+ hours before the deadline, cause usually only 5-10% of the people who see the post actually test it. That's why I invite all my friends over to test it also. Last day (out of 4) should be dedicated for testing with 10+ people, because you will hear a lot of stuff you never thought about, and when half of them says put a tutorial (for example) then you know it's really needed.
Will give your game another try once I find another person.
