Just... how? In 3 days? It could have used another playthrough for catching errors, and the gameplay is a little plain, but that's nothing compared to how amazing the art, music, and writing are and how much fun this was overall. I'd go into more detail about how much charm everything has, but its getting close to the deadline and I still wanted to fit in a few more games.
I will say though, nothing prepared me for Sumireko. What power.
