this was actually rather challenging, but i'm pretty sure i know where your preset is!! this is brilliant and a really creative game!
i've most certainly lost quite a few things in my life (you will not be forgotten, pokémon x. i almost completed it, too. ;-;), however i'm strangely good at keeping things that other may tend to lose extremely easily. for example, i've been using the same ds stylus for nearly a decade now! (it's got giratina on it, it's way too cool to lose!)
