I do wish it was clearer when the game was over, as I spent about half of my playtime trying to figure out how to get the rest of the grank family to accept the yellow grank standing right before them, before eventually giving up, reading the walk through, and finding out I had already completed the game. this may have been in part because I accidentally sequence broke the game, getting the backpack before relocating the yelow grank, but I am not certain.
