I played this game few years ago and today, while scrolling my download folder I saw it and thought to play it again. IT MADE ME CRY ONCE AGAIN (and games make me cry pretty rarely)
Sister's final message was so bittersweet (it made me cry the most), I loved characters development and how comforting the ending was-- It was so good! This whole "I'm doing it for your own good" was nicely written and it showed how she deeply cared, but also abusive behavior very well :'33
Only thing I'd consider as a con here was no saving option and unpleasant sound from overlapping flowers after dreaming. Saving because while talking to Shiori I clicked phone and jumped to Senko. When panicking I turned game off and had to play from beginning x'D
It's a shame that it's not popular, you deserve it so much!!
Sorry for any mistakes
