It showed me a 30 second unskippable video ad before the first level would play. The first level took about as long to finish as the ad took. As soon as I finished the level it went into another 30 second unskippable video ad. So I quit the game and deleted it. Congratulations on your two ad views. I hope it was worth it.
As for the level I played, I assume this it more of a toy than a game. There’s no “lose” state, you just keep turning the control until “gravity” gets the marble to the funnel. It could be a nice zen type toy, or a good game for young children, as long as you aren’t put off by aggressive advertising.
