yeah the ball game seems to make sense for the first part ( maybe shes playing that game? ) but it just doesn't make sense for the rest. 

Also what the heck, whens she coming back to the other world ? I thought that was going to be the gotcha at then end. Would have been funnier if we see the little prince guy as part of the blast.

It was... bizarre, that's for sure. It was funny, though, and the hand-drawn art is really charming. The cursed physics pachinko with no apparent connection to the story gameplay is weird, but I think that's a feature, not a bug.
