Thank you so much for such a detailed review! I'm so glad you enjoyed the game and that it left a positive impression.
Regarding the hints: yes, perhaps it would have made sense to create some sort of catalog, marking possible paths to endings and item hints. Maybe I'll do something similar in the next project.
(I can say that the best ending is the same actions and choices as for Uzumaki's ending, but you need to bring water and rinse your eye.)
Regarding the typos, that's true, unfortunately. English isn't my native language, and I was worried the translation would be completely incomprehensible. Thank you for your attention, I will review the text again.
Thank you for playing! Your review is what motivates me to create!
