Nice idea!
Regarding the hide and seek: I know, but it's still really little time. Esp. if you have to waste precious sends to (turn) around. Which by itself wouldn't be that bad if you wouldn't be reset to the start again, meaning waiting, waiting, waiting again, with some short interruptions to screw up. Maybe my brain is just too slow and others will do better. But I wished the challenge would be the same but the repetitions in case of a failure less tedious.
