The game is titled, I swear to God, Freshly-picked Tingle's Pink-colored Rupee Land. The game has immediately been nominated for Greatest Title In Video Game History.

I can't tell what the game is about, but given the counter in the upper right corner it seems like he has to collect a million rupees, maybe? Probably by doing lots of little quests for townsfolk and such. Who cares, it's got Tingle and an old man with a rupee for a head.
