Fun but buggy

I liked it while it mostly worked. I just lost my $9 “investment” purchase and all game progress suddenly and there’s no way to get anything back in game. The bug report feature in game does not work. The yen rewards you can find in game- kitten and gift rewards - often do not add into your in game bank account. If the game becomes stable and I can get my purchase back I’ll return. This game has lots of potential and I hope the bugs get fixed
